Still exists in 31-rc2.

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).

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

Can anybody else help look at this issue? I really have no idea why this could
happens.

Resolved, it just required a configuration change.

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).

And since you have an 8G machine, that value is only about half of the

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

This lockdep report isn't triggered by 2.6.31-rc2 anymore.

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.

This is caused by selecting a format (no longer / not) supported. Please make
an strace of the failing programm so we know what it requests.

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

It should be still listed 2.6.30.1 does not fix it. still not tried

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.

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:

Given the last comments from Michael I think this should be closed as "not
a bug". The observed behavior is intended.
See: http://lkml.org/lkml/2009/6/29/232.

I still have not received any reaction from the ACPI maintainers to the
bug or the proposed patches.

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.

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.

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
drv_remove_interface(local, &conf);

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
required to make it race-free against RX.

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.

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.

Hi,
The bug is still present in v2.6.31-rc4, it's still fixed by the patch
(see below) suggested as a test by Johannes.

Sorry, this completely dropped off my radar, I'll take a look today.
Thanks for reminding me.
