Although it shows gcc2.96 above, my kernel is built with:

Linux version 2.2.18-1NSRI (mharris@asdf.capslock.lan) (gcc

The Oops occured during system idle time. Nothing significant
was occuring on the machine. The only thing I can think of is
that last night I used my CD burner with xcdroast for the first
time in 2.2.18. xcdroast was still running when i saw the oops.
Netscape shows up in the Oops report, but Netscape was not
running when I found it. The system was not hard locked, but was
able to shut down. Upon rebooting, I had to mount read-only, and
do fsck manually (forced) on all fs's. 2 partitions had serious
problems /var/log, and /var/spool. A lot of log files got
trashed in the process.
