I have some issues with this kernel (both issue are reproductible on two different computers):

- i cannot login with xdm, as soon as i login, the X server restarts. Login with startx works (.xinitrc is a symlink to .xsession) It works fine with 2.6.15-rc5-mm1.
If you need any log please ask.

- there is a warning when pinging an inexistent ip (it works fine with 2.6.15-rc5-mm1 too)

casaverde tonfa # ping 192.168.1.42
PING 192.168.1.42 (192.168.1.42) 56(84) bytes of data.
WARNING: kernel is not very fresh, upgrade is recommended.

from iputils source code (ping.c):

} else {
        static int once;
        /* Sigh, IP_RECVERR for raw socket
         * was broken until 2.4.9. So, we ignore
         * the first error and warn on the second.
         */
        if (once++ == 1)
                fprintf(stderr, "\rWARNING: kernel is not very fresh, upgrade is recommended.\n");
        if (once == 1)
                return 0;
}

dmesg and config are attached, please ask if you need something else.

Hi,

I see three problems, but they are unrelated, so I'll describe them separately in replies to this message.

Greetings,
Rafael

It is impossible to resume from disk on x86-64 machines due to the changes introduced by the x86_64-hpet-overflow patch. The problem is known (appeared in -mm1), but there's no official fix yet.

The appended patch fixes the issue, although I'm not sure if this is the right fix.

The evdev driver is still broken due to the wrong order of arguments of copy_to_user() in evdev_event_to_user().

The following patch fixes this issue.

I added the correct version to my tree so next time Andrew pulls from -mm it will be there.

<0>Kernel panic - not syncing: Aiee, killing interrupt handler!

to appear from time to time when it's being loaded (20% of times or so). If it loads successfully, it seems to work fine.

Can you poke around in gdb, see which line it's dying at?

It looks like at the line 620. At least here's what gdb told me:

Line 620 of "ehci-hcd.c" starts at address 0x69c3 <ehci_irq+211>
and ends at 0x69e2 <ehci_irq+242>.

On my tree that's

	if ((status & STS_PCD) && device_may_wakeup(&hcd->self.root_hub->dev)) {

It's best to actually send a copy of line 620 - kernels vary a lot, and many developers won't have that particualr -mm tree handy.

The way I normally do this is to do gdb vmlinux' and then l *0xffffffff880ad9d0'. If that lands you in some inline function then poke around, displacing the EIP by +/- amounts until it lands outside the inlined function so you can see the callsite.

Anyway. Greg's tree seems rather buggy lately..

Yes, that's it.

Does it work for modules too?

Well ...

Beer is proof that God loves us and wants us to be happy - Benjamin Franklin

Ah. There are certainly ways of doing this - see the kgdb documentation. Or you can work out the module load address, gdb the module and do the appropriate arithmetic I guess.

Generally I just statically link anything which I want to play with.

Still, the oops is from a module. I could link it statically for debugging, but then the address would be different to the one in the oops.

Anyway, please tell me if my reasoning was correct: I thought I couldn't figure it out based on the absolute address, but I could use the displacements. Namely, it followed from the oops that the problem occured at the address {:ehci_hcd:ehci_irq+224}, which is at the offset 224 wrt ehci_irq, so I did:

gdb drivers/usb/host/ehci-hcd.o

In gdb I did:

info line ehci_irq

and it told me the address the line started at, so I added 224 to it and got the line 620.

That's a good way of doing it.

You can do the arithmetic yourself like that, but it's easier to just type

        info line *ehci_irq+224

and let gdb do it for you.

What happens if you make that line read

	if ((status & STS_PCD) != 0) {

and ignore the root hub thing? There's some confusion about when the root hub becomes available ... it should be done a lot earlier than it is now, like before any HCD code may need to rely on it.

- Dave

So far, so good. It works and hasn't triggered the oops yet. I'll report if there's anything wrong with it.

Greetings,
Rafael

I suspect that should be safe to merge for 2.6.15, and it might be worth considering that. You were using kexec() right?

- Dave

No, I was not. Why would that be important?

Rafael

Just trying to keep the symptoms straight, that's all.

When booting this kernel with vga=791 like I normally do, the kernel hangs on boot. Booting with vga=normal works just fine.
I don't have very much info since as soon as the videomode is switched I get a small rectangle of messed up colours in the top left corner of the screen (the rest is just black) and then it hangs - even the keyboard is dead, I have to powercycle the machine.
Nothing makes it to the logs and I don't have a second machine atm to get logs via serial console or netconsole.
I've got the vesafb driver build in, none of the other fb drivers.

Fix vesafb hang when scroll mode is REDRAW.

Sorry about that. This particular hunk was missing in the vesafb_trim_pan_display.patch

No problem, it happens :)

I just rebuild 2.6.15-rc5-mm2 with that patch applied and I can confirm that it fixes the problem.
So, I guess I should add

Andrew, could you please merge that patch from Antonio?

One small detail; With 2.6.15-rc5-mm2 I see a small (rather insignificant) difference in behaviour compared to 2.6.15-rc5-git1 just at the time when the video mode is switched at boot. With 2.6.15-rc5-git1 it goes straight from the text mode display to the graphical one with the boot logo in the top left corner. With 2.6.15-rc5-mm2 + your patch I get a brief, split second, image with random green/grey/white pixels in the location where the penguin appears a few ms later - then everything is normal.
No big deal and it doesn't bother me, just thought it might be something you'd want to know about...

Hello Andrew,

Yes, Yes, Yesss. THANKS! Me not worthy, me bow before Con and Andrew ;-) As for apache/python voting rules, here's my +1 for vanilla inclusion.

Anyway this makes me think. I remember Con saying that SCHED_BATCH relies on his staircase scheduler. I understand this is kind of a rewrite for the current scheduler, right?

Best regards,
Maciej

Hi Maciej

I missed this announcement (been on leave for a while). This SCHED_BATCH implementation is by Ingo and it it is not "idle" scheduling as I have implemented in the staircase scheduler. This is just to restrict a task to not having any interactive bonus at any stage and to have predictable scheduling behaviour I guess.

Cheers,
Con

Yes. SCHED_BATCH in Ingo's implementation is more like turning off the interactive setting in staircase, and the idle scheduling staircase offers is extremely useful.

Fairly standard in Unices but prone to all sorts of priority inversion starvation scenarios so very few implement it. In freebsd for example you can use their idle scheduling only if you are root to prevent this starvation - which kind of makes it useless in practice. My implementation is fairly robust at avoiding the priority inversion problem - at least I haven't seen a bug report about it for years since I address it :)

Cheers,
Con

FYI, the 6.1.6 version of PlugSched for 2.6.15-rc5-mm2 that I announced yesterday applies the same SCHED_BATCH semantics as Ingo's patch to the ingosched, nicksched, zaphod and spa_ws schedulers (i.e. it suppresses interactive bonuses for tasks in the SCHED_BATCH policy class). As spa_no_frills and spa_svr do not have interactive bonuses there is no change to their semantics. The staircase scheduler in PlugSched will be updated to the same SCHED_BATCH as the stand alone version in due course.

This patch adds a module cs5535 under arch/i386/kernel/, but there's already a module of the same name present under drivers/ide/pci/.

This is a problem if both are modular since two modules of the same name are not possible.

Hi Adrian,

Thanks for pointing that out. I'll use a different name.

Perhaps the cs5535 ide module should also be renamed to something more sane, like "cs5535-ide".

Ben

Historically all chipsets for IDE have been known by the chipset name. Its already changed for the new sata layer. Its probably better to rename the gpio type module, if indeed its even worth having in the kernel (which I'm dubious about)

Locked up on boot just after

"USB 2.0 initialised, EHCI 1.00, driver 10 Dec 2004",

where I'd expect to see the first "USB hub found" message.

Hi Andrew,

the following patch fixes the issues in
s390-introduce-struct-channel_subsystem.patch and
s390-convert-proc-cio_ignore.patch.

s390: Fix missing release function and cosmetic changes.

- Use kzalloc() in blacklist.c.
- Kill unwanted casts in blacklist.c.
- Provide release function for struct channel_subsystem.

Booting a SMP built kernel with 'nosmp' just hangs at the VFS layer, with the message about 'not being able to find root device sda1'. sda is a SATA drive on an Intel ICH5 controller:

I would have to double check, but I think it even missed the USB keyboard.

Yes. I have just tried with 2.6.16-rc1-mm2, and the result is the same. No root device.

The nosmp-booted kernel looks much much slow than the SMP one, it takes ages to detect devices like usb ones, and even spent about 20 seconds here:

and it did not detect any drive, so the no-root-device error. This one can be a detection timeout, but as I say also the USB detection is dog slooow.

Need some info ? .config, or the like ?

Hi,
I've been testing this also. I also see the problem. I don't yet know what to do about it, but it's easy to reproduce. I'll continue to look at it.

For a temporary workaround, booting with "irqpoll" might help, but that's not the real solution IMO.

Hi,

I've just had my kernel suffer a meltdown with 2.6.15-rc5-mm2, there was a massive amount of console output streaming for an hour or so till I got control but this was logged in the messages log immediately after it went amiss.

I'm about to run up -mm3 but didn't see any obvious fix for this so possibly it's still a problem in that one too?
