[NTLUG:Discuss] Interesting kernel panic

[Leroy Tennison]

Was moving hard drives around and when I went to boot I got:

mount error 6 mounting ext3
mount error 2 mounting none
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing.  Attempted to kill init!

Went into repair mode and tried to fdisk (or parted) /dev/hda, both 
failed.  Looked in /dev, only hdb existed.  Shut down and looked.  Sure 
enough the only drive in the system was jumpered as a slave.  Apparently 
GRUB's understanding of (hd0) and the kernel's understanding of /dev/hda 
are different because GRUB loaded the kernel.

Just thought I'd mention it in hopes it helps someone else.
