kernel-generic: For filesystem support, or if you need to load support for a SCSI or

Fatal: VolumeID read error: sector 0 of /dev/sda not readable

OUCH!

I read this: http://unixadmintalk.com/f11/lilo-fails-dev-sda-not-readable-65533/

It appears to help:

root@slackbox:~/kernel-patches# lilo
Warning: bypassing VolumeID scan of drive flagged INACCESSIBLE: /dev/sda
Warning: The boot sector and map file are on different disks.
Added Windows *
Added Linux
2 warnings were issued.

Will reboot then test to see if this upgraded kernel is still vulnerable...
