2.6.13-rc3-mm3

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.13-rc3/2.6.13-rc3-mm3/

- Added the anonymous pagefault scalability enhancement patches.

I remain fairly dubious about this - it seems a fairly specific and complex piece of work to speed up one extremely specific part of one type of
computer's one type of workload. Surely there's a better way :(

The patches at present spit warnings or don't compile on lots of architectures. x86, x86_64, ppc64 and ia64 are OK.

- There's a pretty large x86_64 update here which naughty maintainer wants in 2.6.13. Extra testing, please.

- Dropped git-net.patch (davem's net devel tree). I'm seeing weird TCP hangs. I'm fairly sure they're present in mainline, but was unable to reproduce it without git-net.patch when I was actually trying.

The patches provide the basis for more work on this issue. But we need to start somewhere. The specific issue addresses in the initial patchset is becoming a common case for multi-core applications.

I have just sent a fix to you this morning when I got your messages. Sadly I do not have access to the architectures that failed (arm, alpha and ppc32) but the fix simply removes code that is not used for these arches.

ARM can't support atomic page table operations as such - the Linux view of the page table is separate from the hardware view, and there's some CPU specific code which translates from the Linux view to the hardware view.

Looking at the actual patches, particularly pte_xchg-and-pte_cmpxchg.patch combined with the above, the ARM solution would be to go back to using non-atomic operations here (since we can't do this atomically.) Also, since the MMU will only ever read from the page tables, I don't think we need to play any games with clearing out ptes before we replace the value.

Yes. The patches fall back to nonatomic operations for ARM.

Ok. Then you can use a part of the patches. Define ptep_xchg and ptep_cmpxchg for ARM so that you do can avoid intermittently clearing ptes.

Here is the patch that I sent to Andrew in the morning:

Thanks.

This bit is no longer needed, since alpha-fix-statement-with-no-effect-warnings.patch got dropped.

OK

BTW, -mm3 works fine for me on two AMD64 boxes except for one thing:
On Asus L5D, if I resume the box from disk on battery power (ie the box is started on battery power and resumes from disk), it hangs solid right after copying the image (100% of the time). If it is resumed on AC power, everything is fine.

Well, -mm1[1-2] did the same thing so I think I'll create a Bugzilla entry and start a binary search. :-( The -git[5-9] kernels are not affected by this issue.

Greets,
Rafael

PS
Could you please tell me how I can figure out the order in which the individual patches in -mm have been applied?

- Would you tell me, please, which way I ought to go from here?
- That depends a good deal on where you want to get to.

It's all in the series file:

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.13-rc3/2.6.13-rc3-mm3/patch-series

The simplest way to do a binary search is to grab ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.13-rc3/2.6.13-rc3-mm3/2.6.13-rc3-mm3-broken-out.tar.bz2 and to place all the patches in ./patches/, place the series file in
./series, download and install https://savannah.nongnu.org/projects/quilt/
and do the binary search with quilt push' and quilt pop'.

It's pretty simple - it'll take ten minutes to get the hang of it. You need to create a separate copy of the series file and edit it to record where you're up to in the search. From experience ;)

Note that if you work from my git import, git has a nice tree bisection option.

That tree may be very helpful if the regression is hidden in one of the git trees imported into -mm, as it allows you to pinpoint the exact change
-- as opposed to "it happened somewhere in git-large-foobar-update.patch".

Hi,

Andrew Morton:

*checking* Apparently not, not unless you count the git list's archive. (It's git-rev-list.)

I'll fix that.

Hi,

Andrew Morton:

http://lkml.org/lkml/2005/6/24/234

Basically, you do this:

$ set -o noclobber
$ git-rev-tree --bisect ^good1 ^good2 bad > .git/refs/heads/tryN
$ git checkout tryN

(Initially, "good" is v2.6.12 or whatever version last worked for you;
"bad" is "master", thus:

 $ git-rev-tree --bisect ^v2.6.12 master > .git/refs/heads/tryN
)

Build kernel, test. If good, add tryN to the list of good kernels, above; if bad, replace "bad" with "tryN". N += 1. Repeat.

IT'S HERE AT LAST: Rush job; nobody knew it was coming

Hello Andrew,

I have some questions :-)
Reiser4:

why there are undefined functions implemented that currently not in use? This messages appeared first time in 2.6.13-rc3-mm2.

Any why it complains even CONFIG_REISER4_DEBUG is not set? Please have a look at the -->snip

SCSI:

CONFIG_SCSI_QLA2XXX=y ? I haven't choose that one..I never did..and where is the config located? In the place where it is..is no option marked.

Thanks for help,

Greets

That's due to the code using #if CONFIG_xx' instead of #ifdef'.

Someone was doing wrong things in the Makefile. I think that has been subsequently fixed.

I previously posted a patch that got rid of one of these, find it attached again below.

These aren't functions, these are #if FOO where FOO isn't #define'd. In most such cases, changing the #if ti #ifdef fixes the issue (and in some rare cases these warnings fix bugs).

Since 2.6.13-rc3-mm2 the gcc Warning for such things was activated.

It's located in drivers/scsi/qla2xxx/Kconfig.

It shouldn't [1] activate any code, it's simply a helper option that tells whether the QLA* options should be shown.

This patch is wrong since it adds a select to SCSI_QLA2XXX. Please drop it.

Andrew Vasquez had a better fix and is discussing it with James.

Hello Andrew,

here again I have two problems. With 2.6.13-rc3-mm3 I have problems using my SATA drives on Intel ICH6. The kernel can't route there IRQs or can't discover them. the option irqpoll got them to work now. The problem is new because 2.6.13-rc3[-mm1,mm2] work without any problems.

The SATA drives are Samsung HD160JJ SATAII. The mainboard I use is a ASUS P4GPL-X.

Second one is about Intel HD-Codec (snd-hda-intel) on modprobe when loading the module it gives me

Hi!
Sorry for interfering but I have the Asus P5RD1-VD with the Realtek ALC861 (10b9:5461) and with 2.6.13.3 I've got the problem that he doesn't find /dev/mixer or anything after modprobe snd-hda-intel...

After I attached
http://dlsvr01.asus.com/pub/ASUS/mb/socket775/P5RD1-V/Audio_Linux.zip
(which doesn't work) to a mail in alsa-devel they told me...

"[...]

It tries to access the ALi controller in the same way as the Intel controller.

It may be possible that the ALi chip was designed to be compatible with Intel's, but that they got some detail wrong. Or that the driver gets some detail wrong. There's no way to know without docs[...]"

(not in the archive, yet...)

Dirk

OK. Please generate the full dmesg output for -mm2 and for -mm3 and run `diff -u dmesg.mm2 dmesg.mm3' and send it? And keep those files because we may end up needing to add them to an acpi bugzilla entry ;)

Does -mm2 print that `unknown model' message?

Please verify that it happens without the nvidia module loaded.

Odd trace. Do you have CONFIG_KALLSYMS enabled? If not, please turn it on.

Well I did a little mistake..it only worked correctly up to 2.6.13-rc3-mm1 but this dmesg output I have.

Well as I save mm[2,3] are unable to setup the correct IRQs for the devices..and please note that 2.6.13-rc3-mm3 only booted with irqpoll so its in the dmesg output "dmesg.mm3"
Normaly the IRQ routed to something about 1xx now they are 1-21?! Caused by irqpoll?

Yes and mm1 it's a wide problem as I found many posts on ALSA Forums But the big problem behind is...after it oops
My Linux Raid (md) goes bad then..at reboot it gives me more oops and all changes on FS (reiser4) lost..and if I wouldn't use snd-hda-intel as modul the hole system hung at boot.

Mh I tried but my system freezes on boot then. And screen leaves blank.

Thank you Andrew and the other for the great help up to here.

Greets

Well it looks like ACPI committed suicide, so there's probably not much point looking at the other things until that gets addressed.

Would you have time to raise a kernel bugzilla entry for this? Raise it against the ACPI AML interpreter, version 20050708 and mention the above failure. The output of acpidump (from ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/pmtools-20050727.tar.gz) will probably be asked for.

I'm sorry to say that, Yes.

I finially compiled a fresh 2.6.13-rc4-git1 kernel with ck-patch and Gregh-kh patches.

With this kernel non of the problems I had with mm-kernel are present. Here is everthing just perfect..now
I attached a dmesg output for review :-)

The Oops on probing snd-hda-intel gone. It works now ... Mozart rocks :-) I look at the CVS tree of Alsa later.

I finialy converted my reiser4 root to reiser 3.6.

Where I can get acpidumb or what it is called?

Okay, i will do so ... what else we need to back that out.

Like oh my god? ;-)

The pin2=-1 is wrong I think, right?

Sorry for my different mail accounts, gmail have some problems. Let me say, Thanks again for the help Andrew and all others.

Is still regressed as of 2.6.12 for me, at least. Crashes in TSC sync. Talked to Andi about it at OLS, but then drank too much to remember the conclusion ... however, it's still broken ;-)

Matrix is here (see left hand column).

http://test.kernel.org/

Example boot log is here:

http://test.kernel.org/9447/debug/console.log

Does Eric's recent fix fix it?

From: Eric W. Biederman <[email protected]>

sync_tsc was using smp_call_function to ask the boot processor to report it's tsc value. smp_call_function performs an IPI_send_allbutself which is a broadcast ipi. There is a window during processor startup during which the target cpu has started and before it has initialized it's interrupt vectors so it can properly process an interrupt. Receveing an interrupt during that window will triple fault the cpu and do other nasty things.

Why cli does not protect us from that is beyond me.

The simple fix is to match ia64 and provide a smp_call_function_single. Which avoids the broadcast and is more efficient.

This certainly fixes the problem of getting stuck on boot which was very easy to trigger on my SMP Hyperthreaded Xeon, and I think it fixes it for the right reasons.

I believe this patch suffers from apicid versus logical cpu number confusion. I copied the basic logic from smp_send_reschedule and I can't find where that translates from the logical cpuid to apicid. So it isn't quite correct yet. It should be close enough that it shouldn't be too hard to finish it up.

More bug fixes after I have slept but I figured I needed to get this one out for review.

Wheeeeeeee! that does indeed seem to work. Nice job.

Eric, when you have a final version, throw it over to me, and I'll give that one a spin-test too ...

Thanks!

M.

Welcome. I hadn't how many people were tracking this.

With respect to the fix that is final. The rest of the bug fixes in my queue are for other problems.

Mostly my concerns are with respect to apicid vs logical cpu numbers that I'm not certain are handled properly in the code. genapic_flat doesn't seem to do any translation. And I don't recall if boot_cpu_id is an apic_id or a logical cpu number. On most hardware it is 0 in either case so it doesn't matter.

NUMA-Q boxes are still crashing on boot with -mm BTW. Is the thing we identified earlier with the sched patches ...

http://test.kernel.org/9398/debug/console.log

Works with mainline still (including -rc4) ... hopefully those patches aren't on their way upstream anytime soon ;-)

M.

Oh, thanks. That's about 8,349 bugs ago and I'd forgotten.

Well can you identify the offending patch(es)? If so, I'll exterminate them.

Yup, backing out that one patch definitely fixes it. There was an earlier thread with Ingo about doing some possible debug on it, but to be honest, I haven't had time to play much beyond the initial ideas we tried.

Still broken in 2.6.13-rc5-mm1, any chance you could back this one out until it gets fixed? that way I can still test with that platform (plus it'll stop it from getting accidentally merged ;-))

Thanks,

M.

OK, and one last one ... on a more postitive note. rc3-mm3 does indeed fix the problems crashing on boot I was having on PPC64 with -rc3-mm2. I'll close the bugzilla bug.

Thanks!

Serial console is broken on ia64 on an HP rx2600 machine on 2.6.13-rc3-mm3. When kernel is booted up with "console=ttyS,...", no output ever appears on the console and system is hung. So I booted the kernel with "console=uart,mmio,0xff5e0000" to enable early console and here is how far the kernel got before hanging:

Serial driver failed to find any serial ports. I am using defconfig. A 2.6.13-rc3 kernel (no mm3 patch) compiled with defconfig boots up fine and finds all serial ports.

OK, thanks. There have been a few serial driver changes recently, but there's also a tremendous ACPI patch in -mm. I'm wondering about those ACPI error messages:

Does the above happen on 2.6.13-rc3 or 2.6.13-rc4?

Well it did claim to find an 8250 controller.

If you have time, it would be useful if you could obtain the 2.6.13-rc3 dmesg output and do

	diff -u dmesg-2.6.13-rc3 dmesg-2.6.13-rc3-mm3

and send it, thanks.

No, I do not see this on 2.6.13-rc3. It does seem ACPI is busted on 2.6.13-rc3-mm3 which is leading to kernel not being able to scan PCI bus and set up IRQ routing.

Here is the diff:

OK, thanks. Could I suggest that you raise a bug against ACPI 20050708 at bugzilla.kernel.org containing the info we've generated thus far?

And thanks for testing -mm: we really don't want to permit this to leak into mainline...

Your rc3-mm3 boot is also missing this:

IOC: zx1 2.2 HPA 0xfed01000 IOVA space 1024Mb at 0x40000000

So something's busted with ACPI. Both the IOC and the rx2600 serial ports should be discovered via ACPI.

The above patch causes the BUG below on the Zaurus (arm pxa255 with preempt enabled). This can only be due to the suspicious looking changes to kernel/softirq.c in that patch...

Hello,

something broke the sonypi driver a bit after -mm2:
I can no longer set bluetooth-power for instance, and it logs these messages:

sonypi command failed at drivers/char/sonypi.c : sonypi_call2 (line 605) sonypi command failed at drivers/char/sonypi.c : sonypi_call2 (line 607) sonypi command failed at drivers/char/sonypi.c : sonypi_call1 (line 594)

setting/getting brightness, getting battery/ac status still work.

The ioports assignments have changed a bit between -mm2 and -mm3:

Can you do a `patch -p1 -R' of the below, see if it fixes it? It probably won't.

Also please test 2.6.13-rc4-mm1 which is missing the acpi tree...

Thanks.

Make sure that input_work is not running when unloading the module; submit/retrieve key release data into/from input_fifo in one shot.

Didn't help, and -rc4-mm1 has the same problem.
Also tried with CONFIG_ACPI=n and with cardbus disabled, no change. Added a few debug lines to the module:

brightness for instance does not use the sonypi_callX() functions, and it works. cat /dev/sonypi produces no more output either, and interrupt count for sonypi does no longer increase when I press a hotkey or close the lid.

Thanks,

Found the cause:

Applying this dropped patch to -rc3-mm3 and -rc4-mm1 fixes it.

Thanks,

 Manuel Lauss

Wonderful, thanks. So does that mean that 2.6.13-rc4 doesn't work?

OK, I'll bring it back again.

Yes, sonypi is busted in -rc4 also.

ie the difference is that the PCI cardbus resources have been moved from inside PCI Bus #2 to outside of it, and as a side effect the sonypi device just happened to be allocated inside the Cardbus IO space.

Now, this is really unlucky. There are two issues here:

- the -mm2 iomap just _looks_ better. I can't tell what the exact difference is, but it looks like one of the PCI resource allocation patches got reverted or re-applied.

However, I'm almost positive that this is the Intel transparent bridge thing, and it doesn't really matter where the CardBus resources got allocated. So the _real_ breakage is probably due to a totally unrelated issue:

- The SonyPI driver just allocates IO regions in random areas. It's got a list of places to try allocating in, and the 1080 area just happens to be the first on the list, and since it's not used by anything else, it succeeds (never mind that it's on totally the wrong bus).

and I think the real bug here is the SonyPI driver.

It should either use an IO port in the legacy motherboard resource area (ie allocate itself somewhere in IO ports 0x100-0x3ff), _or_ it should play well as a PCI device, and actually try to work with the PCI IO port allocation layer.

So instead of just saying "I want port 1080" (which may be on some other bus entirely), it _could_ (and should) do something like

	/*
	 * Use "device resource 6" for this: it's traditionally
	 * the PCI ROM resource, but we don't have a ROM, so we take it
	 * over for our special IO region.
	 */
	struct resource *res = dev->resource + 6;
	int ret;

	res->flags = IORESOURCE_IO;
	ret = pci_bus_alloc_resource(dev->bus,	/* bus */
			res, 			/* resource */
			SONYPI_TYPE2_REGION_SIZE, /* size */,
			SONYPI_TYPE2_REGION_SIZE, /* alignment */,
			PCIBIOS_MIN_IO,		/* Min starting pos */
			IORESOURCE_IO,		/* IO type */
			pcibios_align_resource,	/* Standard alignment */
			dev);
	if (ret < 0)
		return -ENODEV;

	.. use port "res->start" ..

which should do the right thing.

Stelian? The above is untested, but it should give roughly the right behaviour - you might need to tweak it a bit, but I think it should be a lot better than just picking random IO ports out of your hat and seeing if they are already used by something else...

Linus

On three different intel-vaios, I've seen the sonypi device always located at ioport 0x1080. Even the windows driver on these models always allocates the 0x1080-0x109f io-range for it.

 Manuel Lauss

I think that's how the Linux driver IO list was gathered - looking at where it tends to sit by default.

And the thing is, that would actually be ok too (as I sent in a separate email to Stelian later) - if the BIOS actually sets it up at 1080, we could easily just make a PCI quirk that marks that region _early_ in the bootup sequence as being reserved for SonyPI. That would make any later PCI allocation requests know to avoid it.

The problem with the current setup is that the SonyPI driver is a perfectly regular driver, and thus obviously loads _after_ a number of other drivers, and the PCI setup code in particular. So what has happened is that we've set up other PCI IO regious without knowing - or caring - about the SonyPI driver, and then the SonyPI driver comes along and says "oh, btw, I want that region".

And _that_ cannot work reliably. If you have a specific pre-allocated region that you want (or must have - some regions are fixed because of things like ACPI tables or SMM etc that depend on them), then you need to tell the world about it _before_ it starts allocating anything else, because otherwise the allocation routines obviously cannot know about that fixed thing.

So what the sonypi driver does now is wrong, but there are two choices to do it right: tell the PCI subsystem early (traditionally done as a PCI quirk in drivers/pci/quirks.c, but you could possibly also make it as a driver-specific "subsys_initcall()" - but only if your driver is always compiled in, which sonypi isn't), or then allocate it nicely later.

It's the combination of the two that is bad: "just tell somebody later" doesn't work. They may say that it's easier to get forgiveness than ask for permission, but that's not true in kernels. Because if you do something wrong, the device simply won't _work_, which is exactly what happened here ;).

Linus

Those are not really random, the list of IO regions available is given in the ACPI SPIC device specification. The list is hardcoded here because the driver does not (yet ?) use the ACPI services for initializing the device, and experience has shown that the list does not vary with different models.

this cannot be done, because the regions are already defined, and are not in the legacy area.

sure, but the SPIC device is not really tied to a specific PCI device (it is for the 'type1' models, but not for the 'type2' ones). That's why the sonypi driver is not a PCI driver but relies on a DMI ident to detect each and every Vaio laptop out there.

Stelian.

Stelian Pop <[email protected]>

[Sorry all for the duplicate, LKML slipped somehow from the CC: line so I'm sending this again]

Since every Vaio laptop out there seems indeed to use only the first IO port range in the list, we can de-nastyify the probe. And if we don't even bother to check for Type1 vs. Type2 devices and we reserve both, then it may be acceptable to do the above.

See the attached patch below which does just that. This has NOT been tested (only compile-tested), and moreover it has a high breakage probability in case some Vaios cannot live with the fixed ioport choice.

Note that this patch will conflict with the recent Eric's one (added in CC:), he may want to rediff his Type3 changes in case this patch gets in.

Stelian.

Mark some IO regions reserved on Sony Vaio laptops because the sonypi driver will need them later, and we don't want another driver to reserve them before the sonypi driver starts.

Does not work on -rc4-mm1. The IO-ports pre-reserved message appears, though. The 2 io-regions are still located under the "CardBus #03" device. Re-Applying "revert-gregkh-pci-pci-assign-unassigned-resources.patch" makes it work again.

 Manuel Lauss

Does the patch in appended message fix that?

Sort of. The 4K cardbus windows are working fine for non-x86 architectures where all IO resources are usually well known and added to the resource tree properly.
However, on x86 there are sometimes "hidden" system IO port ranges that aren't reported by BIOS, so the large (4K) cardbus windows overlap these ranges.

Actually I don't like reducing CARDBUS_IO_SIZE to 256 bytes, because we lose an ability to handle cards with built-in p2p bridges (which require 4K for IO), plus it won't fix Sony VAIO problem.

Tero and Mikael, can you try this one-liner instead?

Indeed, it does fix it (vanilla -rc4-mm1 and your patch)

Thanks!

 Manuel Lauss

The problem with this is that it only papers over the bug.

I don't mind trying to allocate at higher addresses per se: we used to have the starting point be 0x4000 at some point, and that part is fine. The problem is that this also screws us if somebody has a PCI bridge with an IO window that is at a lower address than 0x2000 - now the PCI layer will refuse to try to allocate within it, and you'll replace one bug by another.

Linus

Right, and this hurts the cardbus as well...
But it should be pretty easy to learn the PCI layer to allocate above PCIBIOS_MIN_IO _only_ when we allocate on the root bus. Something like this (completely untested)?

I think you'd have to follow the "transparent" case down.. And even then you'd have the half-transparent case to worry about it.

So I think it would be much easier to just make the change in "pci_bus_alloc_resource()", and say that if the parent resource that we're testing starts at some non-zero value, we just use that instead of "min" when we call down to allocate_resource(). That gets it for MEM resources too.

Something like the following (also _totally_ untested, but even simpler than yours). It basically says: if the parent resource starts at non-zero, we use that as the starting point for allocations, otherwise the passed-in value.

That, together with changing PCIBIOS_MIN_IO to 0x2000 (or even 0x4000) might be the ticket...

Cool! I think it's the way to go.

Tested on alpha. Initially I was concerned a bit about architectures where resources _never_ start at zero (due to some specific bus to resource conversions), but this change is just a no-op for them.

Definitely 0x4000. Then we can get rid of PCIBIOS_MIN_CARDBUS_IO which was introduced exactly for this reason, I guess.

Ivan.

Nice, care to make up a single patch with these two changes in it?

thanks,

greg k-h

Yep, I'll do it shortly, plus some minor additions as separate patches.

Ivan.

Actually, since everybody seems to like the "ignore 'min' if we have a known bus resource" patch, and it was already in my tree, I just committed it.

But you don't need to split up any patches you've already prepared: I can easily just edit away the part I already committed.

Linus

OK, I keep your change here - mostly for Mikael, so he can try that ASAP.

There is a number of x86 laptops that have some non-PCI IO ports in the 0x1000-0x1fff range, and it's quite hard to control the correct order of resource allocation between PCI and other subsystems controlling these ports. Especially with modular kernel. So just increase PCIBIOS_MIN_IO to 0x4000 to prevent any new PCI resource allocations in the problematic range (this limitation must apply _only_ to the root bus resources - see Linus' change in pci_bus_alloc_resource). As PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO are the same now on i386 and x86-64, we can remove the latter.

I'm seeing a problem on ARM with -rc3-mm3 and -rc4-mm1. -rc3-mm2 and -rc4 are fine and looking for the problem reveals the problems start after these patches are applied:

Is this related to the size of the process? Can you do a successful kernel compile w/o X?

Yes that only helps if compilation fails and its alread in rc4-mm1 AFAIK.

Its an embedded device and lacks development tools to test that. I ran some programs which abuse malloc and the process would quite happily hit oom so it looks like something more is needed to trigger the bug...

I thought that might be the case.

Richard

Could you get me some more information about the hang? A stacktrace would be useful.

Well the device is able to run X so I guess that a slow kernel compile would work. At least the embedded device that I used to work on was capable of doing that (but then we had Debian on that thing which made doing stuff like that very easy).

I've attached gdb to it and its stuck in memcpy (from glibc). The rest of the trace is junk as glibc's arm memcpy implementation will have destroyed the frame pointer. The current instruction is a store to memory (stmneia r0!, {r3,r4} ) and the instruction pointer isn't changing...

I agree, it would probably do a slow compile. I have no compiler or development tools on it though and only slow vfat disks other than the internal flash. There are plenty of options to get such things working but it will take me a while to setup.

Hopefully the memcpy clue will mean something?

Richard

IP Not changing? Could it be in a loop doing faults for the same memory location that you cannot observe with gdb? Or is there some hardware fault that has stopped the processor?

I'm not the worlds most experienced user of gdb but I can't see any evidence of a hardware fault and the processor shows all indications of running. It seems likely to be looping with memory faults or otherwise jammed somehow.

Is there anything I can use in /proc to monitor page faults or anything I can do with gdb to help narrow this down?

Richard

Can you run kgdb on it to figure out what is going on?

Run kgdb and see what is going on in the fault handler.

There are some variables in /proc/vmstat that may help:

spurious_page_faults 0
cmpxchg_fail_flag_update 0
cmpxchg_fail_flag_reuse 0
cmpxchg_fail_anon_read 0
cmpxchg_fail_anon_write 0

etc.

Maybe, depending on how easily kgdb cross compiles and how quickly I can learn to use it...

In my case:

spurious_page_faults 0
cmpxchg_fail_flag_update 1359210189
cmpxchg_fail_flag_reuse 0
cmpxchg_fail_anon_read 0
cmpxchg_fail_anon_write 0

That number rapidly increases and so it looks like something is failing and looping...

Richard

That looks like some trouble with the MMU. The time between pte read and write has been shortened through the page fault scalability patches.

Does this patch fix it?
