Hi,
for about half a year now (I think - it could be more), my 5-STABLE
machine has been panicing occasionally and irregularly - about once or
twice a week - during shutdown. (I did multiple updates of the system
during that time, which didn't change anything.) It always happens after
the disks are sync'd and when the machine should either turn off or
reboot.
Here's a backtrace of the latest core dump:
