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
then a a number of dump lines.
The kernel that is working (only other one listed in menu) is: 2.6.32-279.22.1.el6.i686
That is very old kernel. Try removing new kernel, and then reinstalling it, and if that does not work try removing new kernel and installing one before that, then one before that. Something like "yum install kernel-2.6.32-279.22.1.el6.i686" should do it. List all kernels with "yum list kernel*"
Sounds a lot like what Harald was saying. So for the first step I get:
