I ran into a similar problem with the upgrade to 4.2 from 4.1, and help on this list pointed me to the following link: http://bugs.centos.org/view.php?id=1050 In my case, I had more than 1 hard drive, and the second hard drive wasn't usable. I had to remove, I believe, the dmraid package. You didn't mention whether you have 1 or more hard drives.
