Re: kernel panic - not syncing: VFS - unable to mount root fs on unknown-block

In progress ! I built-in LVM driver and compile the kernel with the
-initrd option. I have not more the kernel panic message, but I have a
lot of errors than this :

I/O error ; hda: cannot handle device with more than 16 heads - giving up

I'm astonished, I believed that old .config was operational with a new
kernel (my old was a 2.6.16, the new, 2.6.17).

Regards,
Thibaud.
