Here's an oops and hang from /var/log/messages that happened the other
evening. It kicked in at 4am or so. This was running 2.5.70-mm3 SMP,
PREEMPT, no ACPI, RAID1 on one pair of disks, not root or /boot.
Here's the messages I got in the messages file. The system was
completely hung and needed to be reset to recover:

This appears to be a visitation from the Great Unsolved Bug of the 2.5
series. Someone playing with a freed task_struct.
Correct me if I'm wrong, but this has only ever been seen with
CONFIG_PREEMPT=y?

run for a while.
Is there anything special you want me to do to stress this out?
