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

why don' t you just remove any package from the new kernel which don't work anyways and after that "yum upgrade" again?

But how do I determine what package from the new kernel

i said: and after that "yum upgrade" again man if you remove that broken packages a "yum upgrade" pulls them simply as if they where never be installed and the rpmscripts will generate a new initrd

OK. So...

# yum erase kernel*

...

Transaction Summary

Remove 17 Package(s)

So I am making notes about what is being removed so I can insure that it gets reinstalled with the upgrade.

Well the upgrade is NOT reinstalling all that was erased:

# yum upgrade

Installing: kernel i686 2.6.32-431.20.3.el6 updates 26 M Installing for dependencies: kernel-firmware noarch 2.6.32-431.20.3.el6 updates 13 M

Transaction Summary

Install 2 Package(s)

So looks like I will have to do all the others step by step.

So I made sure that all the packages were reinstalled. I did it step by step and did 'yum install' on:

kernel-headers glibc-devel irqbalance mod_perl perl-Test-Simple redhat-lsb

I then did a reboot and ran down to my NOC in the basement to watch the reboot. I did catch a message on the console about rebuilding initrd, but I don't see a matching message in /var/log/messages.

Anyway I am now up and running. Thank you for the help. And Harald, I agree that if the system boots, it should be possible to get through a recovery to the proper point and not have to reinstall.

Now remember. No big updates when vnced into the remote system. Use 'screen'. Remember use 'screen'. :-)'
