I've seen the same problem on some systems when I was playing around 
with LVM.  The only difference my for-fun machines were initial 
inistall.  When booted into rescue mode, I can mount root file system 
(from LVM volume).  When booting normaly, kernel fails to find LVM 
volumes (and thus no root file system to mount that leads to kernel panic).

Have you got any replies on this off-list, or maybe managed to figure it 
out yourself?
