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.
No, I wasn't using a command line, because I couldn't get the sucker to boot, even though when I did what it told me to do on panic - add rdshell to the kernel line before booting - I could manually assemble the RAIDs, but then it wouldn't mount.
I *literally* started an install (I had a PXEboot one available) with no ks file. About three or four screens in, it presented me with a set of options to install (wipe everything), or... forget what the second option was, and the third was "upgrade", and it showed a dropdown list (which, for me, only had one entry) of the one I'd installed. I chose that, and then clicked for go, and from that point, it was literally about two minutes, and it installed grub, then did some post-install scripts of its own, and told me it was time to reboot.

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.
