mkroot: label / not found

Hello everybody,

This morning I was working normally on my HP PIV PC with FC4. FC has been
installed and working without trouble for a couple of months. Hardware has
not been modified. I was running KDE and suddenly everything stopped
working.

Then I rebooted the PC and got the following messages:

mkrootdev: label / not found
mount: error 2 mounting ext3
ERROR opening /dev/console !!!!: 2
error dup2'ing fd of 0 to 0
error dup2'ing fd of 0 to 1
error dup2'ing fd of 0 to 2
switchroot: mount failed: 22
Kernel panic - not syncing: Attempted to kill init!

I am im big trouble trying to recover my own workstation and a lot of
locally archived email messages :-(

I had been googling with any luck. Any suggestions will be highly
appreciated. Pardon my English since it is not my native language.

Regards,
