Hello,

I got some oops with 'rmmod -a'.

ksymoops 2.3.4 on i686 2.4.0-test3-pre1. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test3-pre1/ (default)
     -m /boot/System.map (specified)

Warning (compare_ksyms_lsmod): module ide-mod is in lsmod but not in
ksyms, probably no symbols exported
Unable to handle kernel NULL pointer dereference at virtual address
