This bug was fixed by commit 781b2ba6eb5f22440afac9c79a89ebd6e3674a60
entitled "SLUB: Out-of-memory diagnostics" by Pekka Enberg
<[email protected]> and dated Wed Jun 10 18:50:32 2009 +0300.

The fault occurred because when CONFIG_SLUB_DEBUG was set, many of the
memory allocations for wireless buffers were increased from O(0) to
O(1) causing memory fragmentation, and eventually there were no
remaining O(1) fragments. This problem is unlikely to affect most
users as none of the distos turn on the above debug option.

This bug should be marked "closed with patch".

Hmm, I'm remembering differently. I thought the root problem here has
only been fixed in Pekka's slab-2.6.git tree with "slub: add option to
disable higher order debugging slabs" and isn't currently in Linus' tree.

It only happens when CONFIG_SLUB_DEBUG_ON is enabled for caches with
sizes that increase as the result of the added metadata.

It has been fixed, at least I did not see it in recent rc4 kernel.

Yup, the fix is in slab.git and queued for 2.6.32. There was some
complaints from Christoph from the patch that need to be addressed
still.

>From what I recall, he asked that calculate_sizes() be called twice, first
to determine if get_order(s->size) increased as the result of the metadata
and, if so, a second time with the flags disabled.

slab_debug=O only disables debugging options that increase the min order
of slab as defined in DEBUG_FLAGS; it doesn't selectively disable some of
them when get_order(s->size) grows. So it's quite sane, like my patch
does, to disable all DEBUG_FLAGS when

get_order(s->objsize) + DEBUG_SIZE_FLAGS > get_order(s->objsize)

without calling calculate_sizes() twice.

We need DEBUG_FLAGS to determine which flags to mask off to reduce the
minimum order, so I don't see DEBUG_FLAGS_SIZE as troublesome.

This is no regression between 2.6.29 and 2.6.30.
In fact we could reproduce the problem with kernel versions:

2.6.27.26 < X <= 2.6.30.3

(Meaning 2.6.27.26 is the last one _not_ showing the problem).

There's some question as to whether this should be considered a kernel
bug. The kernel isn't doing anything wrong; the problem is that
various userspace programs enable autosuspend for devices that can't
support it properly.

I'm currently working on a patch for laptop_mode. The maintainer tells
me there's work going on in the kernel to blacklist USB devices that
don't implement autosuspend correctly (like mice turning their light
off, etc...). Is that true?

No, it isn't. The kernel has no way to tell whether mice behave that
way or not.

The only suspend-related blacklisting in the kernel is concerned with
broken devices that can't be resumed after they have been suspended.
The kernel has to reset these devices instead of resuming them.

My patch is already in Pekka's slab-2.6.git tree at
http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=commit;h=fa5ec8a1f66f3c2a3af723abcf8085509c9ee682

You had proposed http://marc.info/?l=linux-kernel&m=124725166205814, which
moves the mask to kmem_cache_open() and calls calculate_sizes() twice.
That eliminates DEBUG_FLAGS_SIZE, but I don't see that define as being
troublesome since we must define DEBUG_FLAGS to specify what options add
metdata anyway.

Thanks for the update.

Unfortunately, I have no idea about what's wrong here.

Generally, there are three possible areas the problem may be related to:
(1) interrupts,
(2) CPU hotplug,
(3) ordering of the platform callbacks,

but I can't say much more than that.

My prosal was to use the size and objsize parameters. You would only have
to call calculate_sizes() twice when the comparison of the order of size
and objsize would be different.

Doing so would simplify additing future flags. If you do your own
calculations (like in the patch) then you have to replicate the size
calculation from calculate_sizes() somehow. Is the duplicate calculation
really accurate regarding alignment and other special casing?

Ok, fair enough. It seems like a matter of taste in implementation but
your proposal is also more extendable than mine, and I'm definitely not
going to argue your taste vs. mine when it comes to slub :)

I'll write an incremental patch on top of Pekka's for-next branch to
implement your idea.

Subject: [patch] slub: use size and objsize orders to disable debug flags

This patch moves the masking of debugging flags which increase a cache's
min order due to metadata when `slub_debug=O' is used from
kmem_cache_flags() to kmem_cache_open().

Instead of defining the maximum metadata size increase in a preprocessor
macro, this approach uses the cache's ->size and ->objsize members to
determine if the min order increased due to debugging options. If so,
the flags specified in the more appropriately named DEBUG_METADATA_FLAGS
are masked off.

This approach was suggested by Christoph Lameter

Subject: Re: [Bug #13407] adb trackpad disappears after suspend to ram

Hi,

The bug is still present in v2.6.31-rc4, it is fixed by commenting out
{suspend,resume}_device_irqs() in drivers/base/power/main.c as suggested
by Rafael. Any success in reproducing it?

Regards,
Jan

This can no longer be reproduced by the original reporter, so it should
be closed.

thanks,

And 2.6.28.10 is showing the exact same problem as initially reported,
right?

I noticed your /var/log/messages is showing you're using slub as opposed
to slab (which Justin was using, and causing order-0 allocations errors).
SLUB uses order-1 allocations for this cache growth and it's failing
because of memory fragmentation, not because you're truly oom.

The only thing that is immediately apparent that changed in this path over
these kernel versions (there were significant changes to e1000e) is the
CRC stripping. If it's loaded as a module, perhaps you could try

modprobe e1000e CrcStripping=0,0

(assuming you have two adapters).

I've cc'd some relevant e1000e driver people in the hopes they'll be able
to diagnose this problem. Memory fragmentation as the result of page
group changes wouldn't affect order-0 allocations such as this on slab, so
it's doubtful the VM regressed if you can reproduce the problem with
CONFIG_SLAB.

powernowk8_cpu_init() has since been largely modified for cpumask changes
commit 1ff6e97f1d993dff2f9b6f4a9173687370660232.

Kurt, could you try 2.6.31-rc4? If it still hits a bug, please post the
dmesg and your .config.

Yes, that is correct.

Originally I used slab, and as someone wanted me to test slub I tried. The
results looked pretty much the same to me.

I will try that.

I can, as said before, the problem first showed up with slab.

Ozan - can you confirm it broke between 2.6.29 (ie you tested 2.6.29),
and 2.6.30-rc1. If so I have an idea what is going on

>From my last comment on bugzilla.kernel.org:

"I tried with 2.6.30.1 but the problem still persists. I really don't have time
to bisect it, but I can help with any other debugging outputs. I also started
think that my board could somehow be faulty as no other people complains about
a similar issue.

Finally, it seems that the problem is available with 2.6.28, so the starting
point is still fuzzy to me. I remember that the keyboard was working OK with
2.6.29_rc7 but now it's not.

Maybe we should drop this report from the regression list."


Monday I'll have access to the computer. I'll build and try to find the last working version.
Meanwhile, I'd like to hear about your possible finding.

Thanks,

There have been few changes to parport_pc but one thing recent changed
the probe for SuperIO chips via low addresses and that could be
interfering.

commit e2434dc1c19412639dd047a4d4eff8ed0e5d0d50
Author: Jens Rottmann <[email protected]>

changed the behaviour slightly (hence asking about which release if it
was a recent breakage). Its also a code area with very few changes so if
you can find which one worked last, you should be able to transplant that
parport_pc into 2.6.current and see if its parport or acpi triggered
breakage.
