Description of problem:
I've been running FC3 test1,2,3 and fresh install FC3 roughly Nov9.
yum update'd kernel-smp.i686 2.6.9-1.678_FC3, kernel.i686
2.6.9-1.678_FC3 . Reboot- failed with the following 
messages- 
mkrootdev /1 not found
switchroot mount failed
mount /initrd/dev failed
kernel panic not syncing  .. blah blah.

e2label verified the labels are correct :
# e2label /dev/sda1

# e2label /dev/sda3

# e2label /dev/sda4

Meanwhile, I updated my laptop with fresh install of FC3
and updated it. kernel-2.6.9-1.678_FC3 boots fine and all
is well. 

In short, it the kernel update boogers up my GX280 -likely
because of SATA . Meanwhile- I am still running kernel-2.6.9-1.667
on the GX280. And- I adjusted /etc/sysconfig/kernel and
/boot/grub/grub.conf to select previous kernel .

Version-Release number of selected component (if applicable):
kernel-2.6.9-1.678_FC3

How reproducible:
Always

Steps to Reproduce:
1. yum update 
2. reboot
3. boot- fails same for SMP vs non-SMP kernel
    

Actual Results:  Have to hit power-off button 

Expected Results:  should be no problem to boot as before
