SubjectKernel 2.2.12 oops

This happened this morning. Since the oops message was copied by hand,
some of the stack numbers might be off.

The machine is a pretty heavily-loaded squid box, running in http-accel
mode in front of a bunch of Solaris web servers. It's an SMP i386 box.

webdbdevel:/usr/src/linux# ksymoops -m ./System.map -k ./crash.ksyms -l
./crash.modules -o ./modules < crash | more
ksymoops 0.7c on i686 2.2.8. Options used
-V (default)
-k ./crash.ksyms (specified)
-l ./crash.modules (specified)
-o ./modules (specified)
-m ./System.map (specified)

No modules in ksyms, skipping objects
