FC5 Kernel Panic!

[David Fletcher]

I've got no idea why this is happening. The machine in question is at work, 
and is almost identical to this one. They both have a 3GHz P4 in an Intel 
D865PERL motherboard, both dual boot XP or FC5, both are running a Seagate 
SATA HDD. This one has 2G RAM, but the one at work only has 512M.

This machine gets updated very regularly, but the one at work only gets 
updated infrequently, because I have to run XP to do my work.

When I updated the work machine last week, I received kernel 
2.6.18-1.2257.fc5smp, according to the Grub screen. If I select the 1.2239 
kernel it boots ok. If I select the 1.2257 kernel I get

Uncompressing Linux... Ok, booting the kernel;
Red Hat nash version 5.0.32 starting
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!


I found a thread about a similar sounding problem from a couple of months 
back. It suggested the command

mkinitrd --with=raid456

which didn't help me any. I'm not using RAID on either of these machines 
anyway.

I suspect that because the work machine gets updated so infrequently, sometime 
it has missed something important in an update, that is not now on the 
mirrors because they have been updated again. Am I correct?

Anyway, am I on the right track to fixing this with the mkinitrd command?

Thanks in advance to anybody who can please give me the appropriate magical 
incantation to get the machine to boot the latest kernel.
