oops at slab.c:1441
Hi,
I found the following oops in one of our box's kern.log.
It's a Debian Woody running 2.4.20.
The machine seems to have crashed immediatly afterwards - I have no idea what the user has been doing at that time. There were no messages in the kern.log before for more than 12 hours.
Syslog reports:
