Hi,
I'm trying to debug freezes upon resume from suspend-to-RAM on my
Thinkpad X61s. The userland is a mostly stable x86 Gentoo Linux with
recent X stack. The freeze does not occur always, but it is
reproducable after a few successful suspend-resume cycles. I can
reproduce it because affected kernels will not complete 10
suspend-resume cycles, so this has been my criterion for all the tests I
have done. When the freeze occurs I have seen various things happening.
In most instances the X screen comes up in the state before the resume
works for a few milliseconds and then freezes. In this state the
computer is not reachable by ssh and the only option is to reboot. In
other instances I have also seen X crashing, dropping me to a console
and then freezing. In one inctance (still with gentoo-sources, before I
started testing with mainline) I was able to ssh into the system and
found spurious things in the log. Please see the attachad file
'messages'. On 12:08:33 I connect via ssh as root. I see the process X
occupying 100% CPU and it cannot be killed (kill -9 has no effect). I
tried to reboot the machine with init x6, but this failed. Browsing the
list archive it might be related to what Linus reported here:
https://lists.linux-foundation.org/pipermail/linux-pm/2010-November/029299.html
These problems appear to me as a regression since everything is
reproducibly fine with kernels <=2.6.34, and 2.6.35 seems to be fine too
(although I have tested that less). I started a bisect, see below.
I'm happy to provide any additional information. For now I'm attaching
the following information in the hope that it is useful:
-) Output of dmidecode
-) Output of lspci -vvv
-) Messages
-) log of a bisect I started. I will take some days to finish probably
and I'm running into 'skips' now.
Regards,
Thomas

This warning means that resume took more that 10 s, which is suspicious, but
not a bug by itself.

Well, it would be good if you could find the commit that broke things for
you, but it might be a few different things - ACPI, PCI, graphics driver, etc.
Please check if you can reproduce the symptom using pm_test:
# echo core > /sys/power/pm_test
# echo mem > /sys/power/state
(it should simulate a suspend-resume cycle and get back to the command prompt
in 5-10 sec). You can try to run that in a loop and see if that breaks things.
Thanks,
Rafael

Well, the resume is very quick, at least the display comes up and the
computer starts to react for a very short time, but then freezes.

How do you avoid non booting kernels during bisect? I seem to run into
non-bootable kernels frequently.

Which kernel options do you recommend for this debugging? Currently I
don't have the /sys/power/pm_test node.
Cheers,

Depends. You can use "git bisect skip" I guess.

CONFIG_PM_DEBUG should be set (but don't set CONFIG_PM_VERBOSE at the same
time).

Hi,
Sorry for the delay, only today I was able too look into this again.

I tried this and I can reproduce the problem in this way. Here are some
additional observations:
-) In the tries I did with the debug procedure the problem always
occurred on exactly the 4th resume.
-) I killed X before doing this to make sure that it is not involved,
and indeed, the problem persists.
-) When the resume failed I can still switch consoles with Alt+F?, but
any keys typed into this console are lost, i.e. I can not log in or
anything. The machine is not reachable by ssh, on the console where I
was logged in I do get visual "^C" feedback, although "^C" has no
effect. Everything is frozen.
Then regarding the bisect, I consider my tries as failed. Even using
git bisect skip I am constantly running into non-bootable kernels. How
do people use git bisect? It seems quite useless to me, as all these
patches depend on each other. Probably I would have to try to find the
issues of the non-booting kernels, but I'm not very motivated for
debugging the failures during debugging...
What else can I do to track this down? The failure starts to show
between
625c94df22fb4247c8ccd54635a8ec77cb60d651 (Fri Aug 13) (bad)
and
ab69bcd66fb4be64edfc767365cb9eb084961246 (Fri Aug 6) (good)
Thanks,
Thomas
