Hello,
today I got the following oops while kmod was loading some scsi-modules. This happened while I wanted to access my scsi cdrom drive:
Options used: -V (default) -o /lib/modules/2.2.10/ (default) -k /proc/ksyms (default) -l /proc/modules (default) -m /boot/System.map-2.2.10 (specified) -c 1 (default)
