Actually, it is probably not a grub misconfiguration, and equally unlikely 
to be easy to solve.  The fact that his UUIDs are the same for both the 
working and non-working kernel images argues against there being a grub 
config problem.  If you boot into the "recovery" version of the -14 image, 
you should see a message shortly before the panic indicating that it 
couldn't find a filesystem on the boot partition.

You can try.  ime, this is due to "update-initramfs" not actually putting 
all the necessary modules into the initrd image.  As long as kernel 
2.6.28-13 is working, I'd stick with it until a new kernel comes along, and 
then try that.
