Arch Linux

Can you reproduce the crash with debug symbols and post a backtrace from the coredump? This isn't useful as is.

I cat't get usable core dump on systemd.
But, I found similar reports:
https://bbs.archlinux.de/viewtopic.php?pid=311974
https://bbs.archlinux.org/viewtopic.php?pid=1326769

> I cat't get usable core dump on systemd.
Then I can't really help you.

systemd-coredumpctl dump > /tmp/coredump.700

If you didn't bother to recompile systemd with debug symbols and reproduce the crash, there's no point in me looking at that....

You can install systemd-207-5 along with a debug package from my repo:

[falconindy]
Server = http://repo.falconindy.com/$arch

This will give you a useful core dump to get a backtrace from.

Thank you.

Nothing really to do here -- it's memory corruption which could be the result of a kernel bug.

How are you suspending? Do you have any hooks which might unload/load modules or do anything else?

According to https://bbs.archlinux.org/viewtopic.php?pid=1327084 this has nothing to with systemd 207, and everything to do with linux 3.11.x. So, my suggestion that this is memory corruption due to a kernel bug seems accurate.

Take it to the kernel bugzilla.
