As a heads-up.

This one breaks the fragmentation reduction patch in 32 bit emulation mode. Our test case shows the standard 17 fragmented regions in /proc/self/maps (as in the 2.6 standard kernel) vs the 2 regions in 2.6.12-rc5-mm2 (and before).

Somehow the new way of detecting 32 bit remulation mode seems to fail here.

I'll try to figure out a fix.

Wolfgang

Here is one possibility:

Since rc6 the difference between TASK_UNMAPPED_64 and TASK_UNMAPPED_32 is gone and both are now merged into TASK_UNMAPPED_BASE. Therefore we can no longer check our local base against TASK_UNMAPPED_BASE to see if we are running in 32bit emulation mode. The appended patch uses other (hopefully the right) means.

Tested on x86_64 in 32 and 64 mode (64 bit fragments as desired, 32 bit collapses as desired).

Hi Andrew,

I didn't see any breakage. But I get these two lines during boot:
yenta 0000:02:03.1: no resource of type 100 available, trying to continue... yenta 0000:02:03.1: no resource of type 100 available, trying to continue...

Anyway, my PCMCIA slots seem to still work.

Brice

Fine with me. I'll roll it into my next update.

How did you generate git-netdev-r8169.patch ?

Jeff's 'upstream-2.6.13' includes all the pending r8169 changes and nothing will be merged before 2.6.12 is out. Imho you can safely ignore any r8169 change until 2.6.12 appears.

Hi Soren,

Which kernel are you upgrading from?

Is CONFIG_PNPACPI set? If it is, try whithout it.

If it doesn't work, please try reverting (in reverse order):
gregkh-i2c-hwmon-01.patch gregkh-i2c-hwmon-02.patch gregkh-i2c-hwmon-03.patch i2c-chips-need-hwmon.patch gregkh-i2c-hwmon-02-sparc64-fix.patch
and see how it goes.

Thanks,

Jean Delvare

Hi,

from 2.6.12-rc5-mm2

nope, don't even have CONFIG_PNP set.

yeap, reverting these did the trick, all i2c entries in sysfs are back. :)

thanks alot.
cheers.

Hi Soren, et. al.:

My bad. Although I will redo the hwmon patches soon anyway, here is a patch that you can apply (after reapplying the above) that should get you working again. BTW: I tested it on almost identical h/w as yours, this time with the same relevant config options, against 2.6.12-rc5-mm1. This applies to -rc6-mm1.

---------------

This patch fixes an init order bug between hwmon and i2c/chips, without which many sensors drivers will not initialize properly (in non-modular systems).

We've been seeing an early boot hang on IBM x-series (at least on an x440) with -rc6-mm1. Finally got hold of a box to go search for this and it seems that backing out the three patches below fixes it.

 515  dmi-move-acpi-boot-quirk.patch
 516  dmi-move-acpi-sleep-quirk.patch
 517  dmi-remove-central-blacklist.patch

I am pretty sure it is actually the first one (thats where my bisection search pointed) but I had to drop the other two to back it out. Anyhow, 2.6.12-rc6-mm1 boots on an x440 with these backed out.

Cheers.

Thanks for taking the time to do that - it helps enormously.

The patches aren't terribly important - I'll drop them if nobody sees the problem. It might be an incorrect __init/__initdata/etc marking. But that wouldn't cause an "early" boot hang...

That does indeed make it boot. However ... once it's booted it seems to hit another problem, a hang condition ;-( I suspect it's unrelated. The box is still up and responsive, but cp spins.

I'm still chasing the other boot/hang double problem (amd64), so can't really look at this right now, but if anyone has any bright ideas they want me to try, or wants more info, let me know (machine is still hung in that state).

What patch?

Sorry.

nmi-lockup-and-altsysrq-p-dumping-calltraces-on-_all_-cpus.patch

It does seem to work. But probably needs some cleanup for the NMI errors.

If you give me to know where the problem come from I can fix it and make a cleanup.

It gets a lot of the "dazed and confused" errors. Possibly you just need to disable that part of the handler?

can you try this cleanup patch?
This fixes the problem for me, though I do no like the way it does so very much...

Ok. I can confirm that linux-2.6.12-rc6-mm1 + just this fix boots fine and works. And yes I said works? I can't understand why backing the others out left us with the odd spin hang and this combination doesn't.
I've managed to run 4 sets of boot and kernbench (10 runs) without a hang.

/me feels there is something else ugly in here we don't want but unrelated to this patch.

Hi Andrew,

I suspect you didn't "make oldconfig" before compiling 2.6.12-rc6-mm1. You should have CONFIG_HWMON=Y in .config, and I don't see it. Note that I can't explain why it results in the BUG right above, but it must be related.

If "make oldconfig" doesn't help, try reverting:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc6/2.6.12-rc6-mm1/broken-out/gregkh-i2c-hwmon-03.patch

Thanks,

Jean Delvare

Were there no interesting printks before this BUG hit?

It's due to the kernel running list_del() on a list_head which isn't on a list.

Seems there is an error-path bug in that driver, but I don' thtink the fix will fix it. Please test?

Nope :-(

Will do. But I don't think that's it. I've been adding printks to determine the execution path and it goes through the ERROR3 path in asb100_detect(), which means AFACT that the error path in asb100_detect_subclients() isn't taken:

hm, the tree I have here doesn't do that. What kernel do you have there?

I suggest you work against
http://www.zip.com.au/~akpm/linux/patches/stuff/x.bz2 which is a patch against 2.6.12-rc6 containing everybody's latest everything.

Hi Andrew,

I suspect that the bug will only show when the i2c-core and asb100 drivers (and the relevant i2c bus driver) are built into the kernel. (See my previous post.)

Thanks,

Hi Andrew, Andrew, all,

[Adding Mark M. Hoffman in the loop, as the author and recent modifier of the asb100 driver.]

	i2c_detach_client(data->lm75[1]); <-- HERE
	i2c_detach_client(data->lm75[0]);
	kfree(data->lm75[1]);
	kfree(data->lm75[0]);

Yup, the kernel now boots.

Ok, I'll keep playing around with the kernel to see what I can find out.

(and I'll take a look at
http://www.zip.com.au/~akpm/linux/patches/stuff/x.bz2 as Andrew Morton suggested)

Thanks,
Andrew

Mystery solved.

ERROR3:

	i2c_detach_client(data->lm75[1]); <-- HERE
	i2c_detach_client(data->lm75[0]);
	kfree(data->lm75[1]);
	kfree(data->lm75[0]);

The missing i2c_detach_client call meant that data->lm75[1] was still on the list of i2c devices when it was freed. This was corrupting the list. The ERROR3 path now works on my kernel.

Thanks for your help.
Andrew

Hi Andrew,

Oh my, I had it right under my nose and didn't see it ;) Thanks for the clarification.

Greg, please apply the following patch on top of the hwmon patches until Mark submits an updated version of the whole thing.

Hi Greg,

2.6.12-rc6-mm1, but that was a fix to Mark's hwmon patches, which you just backed out from your tree - so this fix is no more needed (and should unsurprisingly fail to apply).

Trying to fix it up, but a reboot is needed

regards,

Benoit Boissinot

The arm pxa255 based Zaurus won't resume from a suspend with the patches from the above tree applied. The suspend looks normal and gets at least as far as pxa_pm_enter(). After that, the device appears to be dead and needs a battery removal to reset. I'm unsure if it actually suspends and is failing to resume or is crashing in the latter suspend stages.

Is there some documentation on what the above patch is aiming to do anywhere?

Richard

Did you apply just that patch, or are you talking about the whole -mm lineup?

If the latter, please test with only git-arm-smp.patch.

Sorry, I wasn't clear. I had problems with the -mm lineup and tracked it down to the above patch. With the above patch removed, -mm works fine.

(I know there's a number of changes to the arm pxa suspend/resume code in git-arm.patch but they're definitely not causing the problem.)

Richard

I meant to add that git-arm-smp.patch breaks suspend/resume, even applied in isolation against 2.6.12-rc6.

Richard

<grumble>Well, its a bit late for this since (a) stuff has rapidly moved on at rmk towers since 2.6.12 was released this morning, and
(b) I've just asked Linus to pull this.</grumble>

Thinking about what's probably happening, I suspect all the ARM suspend and resume code needs to be reworked to save more state. I'll try to cook up a patch tomorrow to fix it, but I'll need you to provide feedback.

Please note that you may see other ARM breakage over the next month or so - I'm going to be concentrating on merging ARM SMP support, and whatever bashing other people like yourself can give the kernel will help ensure that problems are picked up quickly.

Please don't underestimate the time it takes to wade through all the patches in the -mm tree, find the one causing the breakage, investigate the patch and report it to the person concerned. I'm doing the Zaurus work in my spare time and don't get paid for it. Just reflashing and booting a new kernel probably takes ~15mins on the Zaurus. The copy/clearpage problem took a complete weekend to track down (as it was showing up randomly) and then needed further evenings to debug your patch which is a large chunk of my free time. The Checked-By: line didn't quite give the full picture.

I realise its taken me a while to find enough time to test/debug this kernel but as least you now know there's a problem...

Ok, thanks. I'm happy to test any fixes/patches.

In order to assist with that, can you publish these patches somewhere? That way, I can apply them against a known good Zaurus kernel tree and know straight away if they break anything (diff/patch format would be preferable as my Zaurus trees are all patch based).

On a positive note, something in the later 2.6.12-rc kernels has made a massive difference to the speed on the Zaurus - I suspect the removal of the preempt locks on copy/clearpage. It boots up ~1.5x faster and the speed gain will make a lot of people very happy :)

Richard

This should resolve the problem - we now rely on the stack pointer for each CPU mode to remain constant throughout the running time of the kernel, which includes across suspend/resume cycles.

I'll see what I can do, but I'm going to be working fairly rapidly on merging this, so expect roughly a patch each day. Hopefully though, the later patches will only affect the Integrator platform.

Actually, this patch is probably an all-round better solution.
