[ale] Kernel panic

[Emil Man]

Chris,

I have seen Kernel Panic happen for several reasons in my systems. I once
had a kernel panic because /etc/fstab got messed up and my hard drives went
all out of whack. Grub was looking in /dev/hdb for the kernel image which
was in /dev/hda. I dont know why because all I did was put in a new drive
for a few minutes to test something, the restored everything again as
normal, and poooooffff....

 I would definatelly run fsck on your disks, to see if the filesystem is in
any way corrupt, or if you have bad blocks, etc. Obviously if you are using
a different filesystem, run the appropriate tool. I think fsck is for ext2.
I know I have reiser on most of my boxen and I run reiserfsck or something
along those lines. I use toms for such cases since you obviously cannot fsck
a mounted disk.
