What does your /etc/lilo.conf look like? Did you copy the entry for your
old kernel, including the old initial ram disk? Also, is your root file
system on a SCSI drive? It sounds like the system is trying to boot off
a SCSI drive, using the module from the RAM disk created for use with the
old kernel. If this is the case, the fix is easy - compile the SCSI
driver into the kernel, and forget the initial RAM disk. You can also
create a new initial RAM disk, but if your root file system is off the
SCSI drive, why bother? You need the SCSI drivers anyway.
