Hard drive errors after hardy upgrade

[lesshaste]

Correction: DVD errors (not hard drive errors but I don't know how to change the title of the post).

I upgraded from gutsy to hardy using the network upgrade option (synaptic) and it almost entirely killed my system. The first serious problem seems to be caused by the new kernel. When I boot in the hardy kernel (2.6.24) I get a series of DVD drive warnings. Here all the relevant lines in dmesg

The complete dmesg from the broken 2.6.24 kernel is at http://pastebin.com/f52736624

I can boot using the old 2.6.22 kernel and the problem goes away. Here are the hda lines using 2.6.22

Any ideas? I can provide more hardware information if needed.
