Help with debugging intermittent crash on resume from hibernation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

In about one out of 10 resumes from hibernation, my system resets after
the hibernation image has been loaded. I am hibernating using

# echo platform > /sys/power/disk
# echo disk > /sys/power/state

When testing hibernation using

# echo core > /sys/power/pm_test
# echo platform > /sys/power/disk
# echo disk > /sys/power/state

I was not able to produce the same failure.

I then tried attaching a serial console and booted with
console=ttyS0,115200n8 no_console_suspend. For the failed attempt, the
last messages before the reset are:

[   25.192978] Disabling non-boot CPUs ...

[   26.175874] intel_pstate CPU 7 exiting
[   26.201040] smpboot: CPU 7 is now offline

For the successful attempt, the last messages before the jump in the
time (which I assume indicate that resume was complete) are:

(I uploaded the complete logs to https://dl.dropboxusercontent.com/u/11545826/logfiles.tar.xz).

At least to me, this unfortunately gives absolutely no indication of
what might be going wrong.

Other than trying again with the -rc3 (which I'll do next), is there
anything else I can do to debug this further?


Thanks,
-Nikolaus
