Please move this out from IDE:

It turned out later that issue also happens with *CONFIG_IDE=n* (the problem
was bisected to commit 295f00042aaf6b553b5f37348f89bab463d4a469 which was quite
soon fixed by commit 2ea5521022ac8f4f528dcbae02668e02a3501a5a).

I was working with Richard on bisecting it further during past week but since
we are hitting a whole ton of unrelated kernel problems it takes a lot of
time...

[Richard Atterer]

Hello,

this bug is still present, but so far (despite lots of useful help by 
Bartlomiej) I have been unable to bisect the issue.

We took some of the discussion off-list - here is a summary, with some new 
results at the end:

* I originally bisected the bug and identified this patch as the culprit:
295f00042aaf6b553b5f37348f89bab463d4a469: ide: don't execute the next 
queued command from the hard-IRQ context (v2)

* The fix for 295f000 (2ea5521: ide: fix suspend regression) did not fix my 
problem either.

* After some mails, I switched to CONFIG_IDE=n in the config I use for 
testing (was CONFIG_IDE=m before), because the problem still occurred in 
that case. The result of this:
295f000 (ide: don't execute the next queued command from the hard-IRQ
        context (v2)): ***Works*** with CONFIG_IDE=n
2ea5521 (ide: fix suspend regression): Hangs with CONFIG_IDE=n
1406de8 (2.6.30-rc6): Hangs with CONFIG_IDE=n

I also disconnected my second (PATA) disk at that point, since it does not 
influence the bug. So my system is SATA-only, both the (single) hard disk 
and my DVD writer are SATA.

* I bisected 295f000..2ea5521 and ended up at this as the first bad commit:
9ea09af3bd3090e8349ca2899ca2011bd94cda85: stop_machine: introduce stop_machine_create/destroy.
This turns out to be a bug that was fixed by
a0e280e0f33f6c859a235fb69a875ed8f3420388: stop_machine/cpu hotplug: fix disable_nonboot_cpus

* a0e280e worked for me, so (with increasing grumpiness;) I bisected 
a0e280e..2ea5521. This bisect didn't work, I ended up with a reported "bad" 
commit which was clearly not the problem. The configs and bisect log are at
<http://atterer.net/s2disk-config/>
The bisect log lines with "OK" mean that I went back and booted the kernel 
a second time, to make sure I hadn't mixed something up. But the second 
tries all had the same result as the first.

* Bart analysed that part of the history and suggested trying out 73d5931, 
and if that worked, bisecting 73d5931..2ea5521.

Today I re-tried both 73d5931 and 2ea5521, and it turns out that in both 
cases, s2disk hangs. :-|

By chance, I noticed that the behaviour during the hang is different from 
what I reported before, at least with these two versions. Initially, I 
said that the system would hang after the "s2disk: Snapshotting system" 
with a blinking cursor.
It turns out that actually it hangs for quite a while (maybe 2 minutes?) 
and only then starts to perform the s2disk!! The last lines written are 
"s2disk: Compression ratio 0.24" or similar, and then a line containing 
just "S¦". Afterwards, the system does *not* power off as it usually does, 
but just seems to hang again. (I think I waited for a few minutes, but 
nothing happened.)

Since the last, third bisect did not work, I'm at a loss what to try next.

Cheers,

  Richard

I think that we can safely skip 73d5931 (btrfs merge) then and mark
the previous commit (6ddaab20c32af03d68de00e7c97ae8d9820e4dab) as
the 'bad' one.

Lets also assume that the last 'good' one (according to your last
bisect results) is ce279e6ec91c49f2c5f59f7492e19d39edbf8bbd.

git log ce279e6..6ddaab2 yields 473 commits, mostly looking unrelated
(regulator, scsi, oprofile, parisc, mtd, ext4) but we have also ACPI
and hibernate changes.

Hmm, we added ACPI NVS memory handling there and some machines seem
to have trouble with it.  I think it would be worth to check it first.

Richard, could you try s2disk on some recent 2.6.30-rc kernel while
booting using "acpi_sleep=s4_nonvs"?

Thanks.
Bart

Richard, could you try s2disk on some recent 2.6.30-rc kernel while
booting using "acpi_sleep=s4_nonvs"?

Thanks.

I just tried that with 2.6.30-rc7, unfortunately it doesn't make any 
difference.

It turns out that if I wait long enough (just over 1 minute) both during 
suspend and resume, I *am* able to suspend and resume the machine. I have 
to manually turn it off or reset it though.

Another possibly interesting observation: My DVD writer apparently gets 
reset before the 1-minute hang and my USB hub after the hang.

Cheers,

  Richard

You replied to Jeff that hibernation worked with CONFIG_IDE=n.  What was wrong
with that test?

It didn't work.  That was wrong.

Please at least read the current thread before asking such questions.

Sorry, I was wondering why Richard told Jeff that the test worked at that time.

I should have asked differently or something, perhaps.
