How do I trouble shoot this? I am assuming that I only got a partially completed update.
Try yum-complete-transaction and see what happens.
Well it looks like all the updates 'took' /etc/redhat-release now reports ver 6.5.
But still getting a kernel panic and boot failing. I can fall back to the prior kernel and it will boot. So I tried to copy the lines off the monitor, as nothing is getting logged:
IOMMU: failed to mpa dmn 0 kernel panic - not syncing: VFS: Unable to mount root fs on unknown_block (0,0) Pid:1, comm swapper Tainted: G -------------} 2.6.32-431.20.3.el6.i686 #1
May I offer a suggestion, if it's still not booting on the new kernel? Try bringing it up on the old one, then mkinitrd while running, so the initrd has all necessary drivers.
Oh, another thought: when it gets to the grub boot, edit the kernel line to add rdshell at the end; hopefully, if it fails, it will give you the grub shell, and you can find out where the actual root drive *is*, which is, I think, what it's looking for and not finding in the grub line that tells it where / is.
