A v2.6.30..v2.6.31 diff shows that this is probably exposed by Rafael Wysocki's commit 6905b1f1, which now allows systems with e100 to sleep. If I understand correctly, it looks like these systems simply couldn't sleep before. Is that right Rafael?. I don't think its likely that the commit is a direct cause of the problem, but that the suspend/resume cycle now allows us to see another issue. Maybe e100 is leaking memory on suspend/resume cycles, or something else is leaking memory, or memory is becoming fragmented and the e100 driver is improperly requesting and being failed on an 'atomic' memory allocation  from a heavily fragmented memory map. Or something else.

So we ( Jesse Brandeburg & I ) have some ideas, and I am trying to get a symptom here. and going through the e100 memory allocation code looking for clues.

Dave

Subject: [E1000-devel] [BUG 2.6.30+] e100 sometimes causes oops during resume

Hello,

I'm getting following oops sometimes during resume on my Thinkpad T21
(where "sometimes" means about 10/1 good/bad ratio):

This is caused by ifup scripts that try to bring interface up after
resume.  When I do so manually it doesn't produce error.  System seems
to behave normally despite that error.

This is on 2.6.31-rc9 (with unrelated patch reverted), 2.6.31-rc8
shown similiar behaviour. Neither 2.6.31 nor Linus' HEAD seems to
address this issue.

Probably true, but that wasn't the case for my (I guess
ACPI-controlled) system.

Precisely patch was supposed to "Fix this problem by ignoring the
return value of pci_set_power_state() in __e100_power_off()."

That patch is doing something rather different -- it returns 0, yes,
but it also ignores 'wake' bool as set by __e100_shutdown().  That
seems wrong to me.

Correct patch would be that (hand-made), right?

I can test, or rather -- start testing this tommorow, if this makes
sense to you.

Thanks.

No, it isn't, I must just go to bed earlier than 4AM. :/

Sorry for noise.

Yes please Karol, test with 6905b1f1...removed. I will continue testing 
here too on 2.6.31, though I have not had a repro yet. And are you 
performing a standby or hibernate, I want to be sure that I'm resuming 
from the same state.
Thanks.

I don't use hibernate, I always suspend to ram.

Thanks.

The systems where e100 is not power manageable by any means couldn't suspend
before that commit.  For the other systems, where e100 is power manageable
either with ACPI or natively, the commit doesn't change anything.

I have a couple of test systems with e100 that don't have any resume problems,
FWIW.

Thanks,
