[ale] Fedora-C3 Kernel Update won't boot??

[Mills, John M.]

ALErs -

I ran 'up2date' on a fresh install of FC-3 and among the updates were
 'vmlinuz-2.6.10-1.770_FC3' and its associated 'config-...', 'initrd-...'
and 'System.map-...'.

When I try to boot this new kernel it fails to find any of my disk volumes,
and panics.

Is this something I can fix, or should I instead build the updated kernel
from fresh sources and the old 'config-'?

TIA.
