Strangely the preceding commit works well, so I bisected the kernel
again, this time more carefully and I've got a different result!
(see bisect_log attachement).
It seems to be commit 73201dbec64aebf6b0dca855b523f437972dc7bb
(https://patchwork.kernel.org/patch/1511921/).
Someone on LKML already reported an issue with this commit
(https://lkml.org/lkml/2012/10/18/228) , but Peter
Anvins patch got already applied in newer versions.
Reverting this patch with the recent git clone seems to be difficult
because it already has too much dependencies.
Additionally I've included dmesg dumps of the last good and the bad
kernel version.

It affects really all versions after that commit and the failure happens
every time I try to resume my notebook.
Best regards,
Jonas

I might be able to get my hands on a T43 later this week and see if I can reproduce this. This patch seems more plausible, at least... but still puzzling.

I applied this change to the current 3.8 kernel and it worked!
If you need more test results, just send me patches and I'll try them :)

Hi, that commit is indeed buggy, but it has already been fixed; commit
1396adc3c2bdc556d4cdd1cf107aa0b6d59fbb1e contains the fix.
So to bisect anything between 73201dbec64aebf6b0dca855b523f437972dc7bb
and 1396adc3c2bdc556d4cdd1cf107aa0b6d59fbb1e in a meaningful way you
will have to apply 1396adc3c2bdc556d4cdd1cf107aa0b6d59fbb1e on top.
If 73201dbec64aebf6b0dca855b523f437972dc7b with
1396adc3c2bdc556d4cdd1cf107aa0b6d59fbb1e on top fails whereas the
previous one does, then that is very interesting and something we can
work with.

Hello,
I tried the newest kernel, 3.9 today but the bug is still present.
Applying the attached patch solves the bug for me.

Okay... WTF is going on here? Does pmode_behavior just not get set up
correctly? Since it seems you can get it to wake up with your patch,
perhaps we can get read out the value of pmode_behavior and print it...

Well, you could give me instructions on how to debug this (I'll do
everything ;)) or I could ship you the Thinkpad T43. I guess this would
worth the effort since this bug is somehow critical.

I'll put together a debug patch unless I can trick Rafael into doing

I'm afraid that code has changed quite a bit since I looked at it last time.
[Jarkko Sakkinen seems to have worked on it lately, CCed.]
Jonas, I wonder what happens if you drop the first hunk of the patch (it just
uses a different register, which shouldn't matter)? Does it still help then?
If so, there are still a few things you can do to it, e.g:
(1) drop the
- btl $WAKEUP_BEHAVIOR_RESTORE_CR4, %edi
- jnc 1f
lines,
(2) drop the
- btl $WAKEUP_BEHAVIOR_RESTORE_EFER, %edi
- jnc 1f
lines,
(3) drop the
+ jecxz 1f
line,
(4) drop the
+ movl %eax, %ecx
+ orl %edx, %ecx
+ jz 1f
lines and see what the minimal patch needed for things to work again is.
Thanks,
Rafael

Hello Rafel, first of all, thank you for helping me out :)
You're right, the patch still solves the suspend bug, after removing the first
hunk of the patch and applying it (see attachement:
suspendfix_first_hunk_dropped.patch).

Thanks for doing that detective work!
The only explanation of why this particular patch can help that seems viable to
us at the moment is that we have a memory corruption in the code region modified
by it and the patch simply changes the alignment of the instructions that don't
get corrupted.
It looks like this may be verified by putting a bunch of nops into the region
in question, so can you please check if the attached patch helps too?

Unfortunately, your attached patch doesn't seem to fix the bug.
Hope you still have some ideas to address this issue :)

Well, not really.
We'll need a dump of the wakeup structure from your system I suppose.
I'll try to write a patch to get that over the weekend.

Kind of had to experiment with this since I don't have access to
T43. Did you already try:
- EFER handling only is reverted as it was before 73201dbe.
- CR4 handling only is reverted as it was before 73201dbe.
Thanks.

Can you try 3.10-rc3 by the way? There is a fix in there that *might* make
a difference (although the odds are quite significant).

Hi Jarkko,
thank you for your response!
Can you please be more specific about that instruction? I don't really
know what to do, sorry :/

That's because no one knows how to fix it. Actually, we don't even know
what the root cause of it is. Sorry about that.
Are you still able to make things work again by reverting the commit you
bisected to?

indeed, arch/x86/kernel/acpi/sleep.c tries an rdmsr_safe(MSR_EFER, ...)
and sets WAKEUP_BEHAVIOR_RESTORE_EFER bit on success, however,
on 90 nm Pentium M (Family 6, Model 13), reading an invalid MSR
is not guaranteed to trap, see Erratum X4 in "Intel® Pentium® M
Processor on 90 nm Process with 2-MB L2 Cache and Intel® Processor A100
and A110 on 90 nm process with 512-KB L2 Cache Specification Update".
On Jonas' T43, which has an affected Pentium M without EFER,
rdmsr_safe(MSR_EFER, ...) succeeds and WAKEUP_BEHAVIOR_RESTORE_EFER
gets set, while on resume the corresponding wrmsr traps and thus resume
fails.
The pre-3.7 code snippet incidentally catched this by not restoring
EFER when it would be restored to all 0s.
HTH,
Christian

That does seem like a reasonable explanation.
Does this patch fix the problem? (Comment blatantly ripped off from
your email message.)

Jonas tried your patch and it fixes suspend/resume on his T43, although
IMHO the safest approach would be to just add an exception for
Vendor==Intel && Family==6 && Model==13, or more generally Vendor==Intel
&& !supports_long_mode, as the same erratum also warns about wrmsr
possibly not triggering a GP either.
Anyways, at least on this specific MSR with the Pentium M Jonas tested,
it behaved correctly on every try, so I'd say your patch does the trick,
thank you very much!
As a side note, I found a similar erratum #33 in "Pentium® Processor
Specification Update" for Intel P54C (Family 5, Model 2), which would,
supposed there are P54C systems with ACPI sleep/resume support, result
in MSR 0 (P5_MC_ADDR) to be saved and restored instead of nonexistent EFER.
Kind regards,
Christian

Using vendor matches is not really a great way to deal with things that
can better be handled analytically.
If WRMSR doesn't fault, it is not a problem...

Doesn't really matter, as we'd only read that one after an #MC.

x86, suspend: Handle CPUs which fail to #GP on RDMSR
There are CPUs which have errata causing RDMSR of a nonexistent MSR to
not fault. We would then try to WRMSR to restore the value of that
MSR, causing a crash. Specifically, some Pentium M variants would
have this problem trying to save and restore the non-existent EFER,
causing a crash on resume.
Work around this by making sure we can write back the result at
suspend time.
Huge thanks to Christian Sünkenberg for finding the offending erratum
that finally deciphered the mystery.

Well, we know now. Hopefully we should have the fix in 3.11-rc2 and
then on its way to stable.
