[CentOS] kernel panic/abort during boot

Just did an in-place update from 6.1 to 6.2 on my eeepc 901 (Atom CPU).

during boot, (if I hit ESC to see the boot messages) it says "starging udev"
then nothing else for a few seconds, then a huge register dump scrolls
by. it's too big to see the beginning of it.

If I boot from the prior kernel and look in /var/log/messages, I don't
see any evidence of the failed boot.

I've seen the other thread titled "kernel panic", and it seems to be
due to a missing initramfs, but there is an initramfs for 2.6.32-220.el6
already in /boot, so I don't think that would be the problem.

Can anyone suggest how I would isolate what's going on here?
