Hi Mark,
Would you mind to elaborate your steps of fixing?
I'm using 'yum groupinstall --installroot=/<loopDevice> ...' method, then Install(not update) the newest kernel from cr/ repository.
Did you rebuild initial ramdisk? If so, what's your command to do that? Thanks a lot.

FUNNY you should mention that... I literally ran into that yesterday, with
lots of screaming and yelling. This will sound scary, but isn't: try
reinstalling, but when you get to the screen that asks you what you want
to do, select the radio button for "upgrade", which says it does *not*
format the partition(s). I did that - I had rsync'd / and /boot from
another server, identical, with Linux software RAID. Bad mistake - best
guess is there are some magic numbers in initrd - so I did this. It only
took a couple of minutes, and seemed to not do much more than reinstall
grub and some post-install scripts, and everything was wonderful.
