Hi,

I got a Oops while doing 'rmmod -a'. I done rmmod -a twice and I got
this oops
(non fatal) while sending the second command.

ksymoops 2.3.4 on i586 2.4.0-test3. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test3/ (default)
     -m /boot/System.map-2.4.0-test3 (specified)

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