And that, to me, tells me that the kernel line in your grub.conf is wrong.
Specifically, I'd guess there's a problem with the parameters
root=<whatever> If you're using label, and I apologize if you know this,
it must read root=LABEL=<mylabel> I don't really know if the word label
must be capitalized, btw. For non-labelled, non-UUID,
root=/dev/<partition>, and the root line, as opposed to the root parm on
the kernel line, is the odd (hdx,y), and y is /dev/devy - 1, partition 1
is 0.
