In some 6.x versions the upgrade can go south. I had this happen on one
server, and this is how I fixed it:
I downloaded and burned the release iso. I booted the system from CD, then
in sysinstall, I used the emergency shell. In the emergency shell I
mounted my drives and had a peek. In my case I saw there was no
kernel. So I copied the kernel from the cd to my root / drive. After that
I could reboot from the hard drive, and finished my upgrade.
Hope this helps.
