Kernel panic – not syncing :VFS: Unable to mount root fs on unknown – block (8,19)

What is this problem ?

New kernel. Did we run a make install?
A Pity about that, make install presumes lilo, the other boot loader :-(
Reinstall grub on the hard disk. From memory

grub setup (hdn) e.g. grub setup (hd0)

Otherwise check /boot/grub/menu.lst (LST in smalls) and particularly the root= option. Don't use a label, use /dev/something.

You can also try pressing e on the start screen, and get to edit your boot line.
