Hi!

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

ksymoops 2.4.3 on i686 2.4.13-pre3.  Options used

     -l /proc/modules (default)
     -o /lib/modules/2.4.13-pre3/ (default)
     -m /boot/System.map (specified)
