I upgraded to 4.5 without any problems, but I did have to account for the fact that the new kernel can potentially reorder NICs on certain HP and Dell servers, so all was well after I switched the network cable... See: http://kbase.redhat.com/faq/FAQ_46_10460.shtm
I wonder whose brilliant idea it was to introduce such a major change in a _patch release_?
This has already been hashed out on the nahant-list. Someone from Redhat gave an explanation. I will leave it up to you to decided if the explanation is satisfactory to you or not.
