Do you think you've fixed that oops too? I can reproduce this on
2.4.19-pre2-ac3 kernel by setting 'append = "hdb=noprobe hdb=cdrom"'
in lilo.conf and after booting doing a 'cat /dev/hdb | od' without
having a medium in the DVD drive. BTW 2.5.x crashes horribly when I
enable this append line in /etc/lilo.conf. I haven't had time to track
this down yet, so you might as well give it a whirl. I've got
CONFIG_BLK_DEV_PIIX=y and CONFIG_PIIX_TUNING=y. More of the .config upon
request.
