Thanks for the update.

Last time I remember you managed to collect some ftrace output from the failing
case, but they didn't reveal anything directly.

We know, however, that is [suspend|resume]_device_irqs() in
driver/base/power/main.c are disabled, the issue doesn't show up.

Is that correct?

I'm not sure -- did we verify that somehow? I was running with some
trial patch from you for a long time but it had no apparent effect.

I have not seen the fix yet, but one is being prepared. I think the
bug can be closed.

http://patchwork.kernel.org/patch/34385 should fix your issue (try with 
CONFIG_SLUB_DEBUG_ON still enabled and slub_debug=O on the command line).

Pekka indicated he wanted this fixed in 2.6.31, so he'll probably push it 
to Linus before the 2.6.31-rc3.

Yup, if it's not too much trouble Larry, I'd appreciate if you gave it
a spin before I apply the sucker. Note to regression trackers, I don't
think this should go to -stable because it depends on other patches in
mainline and there's an obvious workaround for the problem (disable
CONFIG_SLUB_DEBUG_ON). Furthermore, it's very unlikely people will hit
this on production configurations anyway.

Pekka,

I have been running the patch for ~24 hours with slub_debug=0 as a
boot option. So far, no problems. My workload has not involved as many
network operations as some times, but my memory has not fragmented.
The output of 'cat /proc/buddyinfo' is as follows:

Node 0, zone      DMA      8      5      5      4      5      5      5
     4      3      0      1
Node 0, zone    DMA32   1804   1585   3007     36      0      0      0
     0      1      0      0

As might be expected, the high-order fragments are gone, but the O(1)
pieces have not been depleted.

Could be a weird interaction between CONFIG_X86_USE_3DNOW and AGP
or "simply" some timing issue.  Either way it means a lot of "fun". ;)

The latter theory can be verified by adding some {u,m}delay() to
agp_generic_alloc_page{s}() and the former one with:

[Jan Scholz]

Hi,

I'm not sure if I experience the same bug on my apple iBook G4 (ppc
7447A, altivec supported PowerBook6,5) or just something very similar.

With v2.6.30-rc1 I noticed, that suspending to ram does not work if my
wireless card is 'up'. The wireless card is an apple airport extreme
card, this is its lspci output:

0001:10:12.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)

I tested suspend like this:

# unload the wireless module
modprobe -r b43
echo mem > /sys/power/state

# wake up works fine

#loading b43
modprobe b43
echo mem > /sys/power/state

# wake up still works fine

ifconfig wlan0 up
echo mem > /sys/power/state

# the box does not wake up, I guess it's not really sleeping, because
# the sleep led is not on

I bisected this and got:

Hi,

I have just checked this on v2.6.31-rc1 and v2.6.31-rc2-214-g34f2547
(I wanted to test this on v2.6.31-rc2 as well, but there I had other
suspend-issues that are fixed in todays v2.6.31-rc2-214-g34f2547)

For both v2.6.31-rc1 and v2.6.31-rc2-214-g34f2547 suspend to ram fails
with the test procedure described below, but it works fine when I revert

Not really, no. __ieee80211_suspend isn't holding any locks that the
cancel_work_sync() calls could require or so afaict...

Jan, can you run with console_suspend=0 (or whatever it is now, Rafael
will correct me if I'm wrong) that should work on your platform, and put
a bunch of printk calls into __ieee80211_suspend in net/mac80211/pm.c to
see where in there it's hanging?

That's just 'no_console_suspend'.

Did that, seems like it hangs in

Ok, thanks! I was going to suggest doing the same in
b43_op_remove_interface in drivers/net/wireless/b43/main.c, but I think
the problem is just that we have an ordering problem and call drv_stop
before drv_remove_interface. I'll try to come up with a fix soon --
might not be able to today though, in the meantime I guess you can just
move the drv_stop call to the end of the function and tell me if that
works -- that would be racy but should be ok most of the time.

I moved drv_stop to the end of the function (see patch below) and now
suspend works fine.

Thanks, that's what I suspected -- I'll take a closer look into what is

This bug was fixed by commit 781b2ba6eb5f22440afac9c79a89ebd6e3674a60
entitled "SLUB: Out-of-memory diagnostics" by Pekka Enberg
<penberg@cs.helsinki.fi> 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.

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.

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.

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.

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.

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.

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

[David Rientjes]

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
<cl@linux-foundation.org>.

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.

 Sorry for the delay i did not have the time to test 2.6.31-rc* until now.
Tried 2.6.31-rc5 the problem persist. The revert still fixes the issue; so
the bug should be still present.

[Jan Scholz]

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

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

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.

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 <JRottmann@LiPPERTEmbedded.de>
Date:   Mon Jun 22 16:51:49 2009 +0100

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.

I've tested on 2.6.30.4 which has apparently this commit, no changes.

I've booted into Ubuntu 8.10 which has 2.6.28. The keyboard was working
correctly eventhough parport_pc was loaded. I removed and re-probed and
the keyboard is gone.

I've set BIOS settings to default, nope.

I'll try bisecting when I find the last-good/first-bad kernel version.

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

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.

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).

Thanks, moved to the list of regressions from 2.6.27.

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.

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

commit 1ff6e97f1d993dff2f9b6f4a9173687370660232.  

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

Nico reported a black-screen regression too.  Subject:

	2.6.31-r2: Xorg: Black screen


  Compared to the other normal brightness problems, with 2.6.31-r2
  xorg starts, but there is no image displayed (neither on internal nor
  external monitor).

  Switching back to console does not change the status, though
  hitting ctrlaltdel reboots the system (i.e.  still up and running
  fine).

  It works with 2.6.30-rc7 (besides sometimes the brightness is
  broken there).


This looks like it might be a post-2.6.30 regression, in which case it
might have a separate cause.


We're having a lot of problems in this area.

Re: [Bug #13624] usb: wrong autosuspend initialization

[list]

I think this should be considered a regression, at least until 
laptop_mode has been fixed to deal with it. I've reported it to their 
mailing list, but it seems somebody has to come up with a patch (I won't 
be able to look into it before mid-August).

There's simply no memory available in ZONE_NORMAL to satisfy the atomic 
allocation; you've been able to allocate beyond the 9708K minimum 
watermark because it's GFP_ATOMIC (and then only to 3641K because of 
ALLOC_HIGH and ALLOC_HARDER).

112116 pages, or 438M of memory, is dirty.

[415964.311369] 827035 total pagecache pages
[415964.311371] 4728 pages in swap cache
[415964.311373] Swap cache stats: add 12746, delete 8018, find 16878/17480
[415964.311374] Free swap  = 16756356kB
[415964.311375] Total swap = 16787768kB
[415964.312141] 2277376 pages RAM
[415964.312141] 252254 pages reserved
[415964.312141] 546309 pages shared
[415964.312141] 1520221 pages non-shared

And since you have an 8G machine, that value is only about half of the 
default dirty_background_ratio setting of 10 to start pdflush from writing 
it out.

What is suspect is almost half of your system's memory is consumed by 
slab.  Have you been able to collect slabtop -o when these failures happen 
to determine whether this is a duplicate of 
http://bugzilla.kernel.org/show_bug.cgi?id=13518 ?

There's simply no memory available in ZONE_NORMAL to satisfy the atomic 
allocation; you've been able to allocate beyond the 9708K minimum 
watermark because it's GFP_ATOMIC (and then only to 3641K because of 
ALLOC_HIGH and ALLOC_HARDER).

112116 pages, or 438M of memory, is dirty.

[415964.311369] 827035 total pagecache pages
[415964.311371] 4728 pages in swap cache

And since you have an 8G machine, that value is only about half of the 
default dirty_background_ratio setting of 10 to start pdflush from writing 
it out.

What is suspect is almost half of your system's memory is consumed by 
slab.  Have you been able to collect slabtop -o when these failures happen 
to determine whether this is a duplicate of

As of yet, the problem has not recurred, when it does, will pull slabtop

Stephan von Krawczynski has this problem with e1000e (but not e1000 or 
tg3) at least as far back as 2.6.28, so this doesn't appear to be a 
regression introduced in 2.6.30.

Given the last comments from Michael I think this should be closed as "not 
a bug". The observed behavior is intended.

Well, I guess the regression here is the apparent lack of documentation, but
now that the problem has been discussed, I guess this is not a problem any
more.

[PATCH 2.6.31] mac80211: fix suspend

[Johannes Berg]

Jan reported that his b43-based laptop hangs during suspend.
The problem turned out to be mac80211 asking the driver to
stop the hardware before removing interfaces, and interface
removal caused b43 to touch the hardware (while down, which
causes the hang).

This patch fixes mac80211 to do reorder these operations to
have them in the correct order -- first remove interfaces
and then stop the hardware. Some more code is necessary to
be able to do so in a race-free manner, in particular it is
necessary to not process frames received during quiescing.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13337.

2.6.31-rc1-git3: Reported regressions 2.6.29 -> 2.6.30

[Rafael J. Wysocki]

[NOTES:
 * I hope you notice the jump of the number of reported regressions after 2.6.30
   was released.
 * Please let me know which of these bugs have been fixed already (ideally
   please also provide the name of the fix commit).
 * The post-2.6.30 reports were flooded by the megre window noise that made
   them very difficult to track.]

This message contains a list of some regressions introduced between 2.6.29 and
2.6.30, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.29
and 2.6.30, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

2.6.30-rc7: Reported regressions from 2.6.29

[Rafael J. Wysocki]

[NOTE:
 Bug entries for which I know there are working patches get the
 RESOLVED / PATCH_ALREADY_AVAILABLE status in the Bugzilla, which
 makes it easier to check if the patches have been merged before sending
 out the list.  For this reason, please let me know of working patches
 for any of the regression list items or (better) change the status of the bug
 entries in case you know of a working patch (in which case please also add
 a link to the patch to the appropriate bug entry).]

This message contains a list of some regressions from 2.6.29, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.29, please let me know

entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
