2.4.5-ac12 kernel oops

From: Colonel (klink@clouddancer.com)

Why the symbol mismatch? Why ignore /proc over the System.map?

The system had very little running (because of prior lockups) during
the morning SQL activity. About 3/4 of a megabyte was being added to
the SQL databases, and that activity had been going on for 45 minutes
prior to the oops. No X, and I was reading email as the only other
load. Daemons: postfix, raid5, xntpd, syslog, cron & kernel. SMP
kernel, built with gcc 2.95.3 released 20010315.

At the time of the oops, there is an cron task that feeds postfix,
which deposits the email into a 3 meg file.
