SubjectOops while inserting sym53c8xx.o
Hi!

I received an Oops while inserting the sym53c8xx.o module. Machine is
the famous Tyan Dual-Athlon board, 2x 1G4HZ Athlon, 1GB RAM:

-v /boot/vmlinux-2.4.13-pre3--00 (specified)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.13-pre3/ (default)
-m /boot/System.map (specified)
