You've got all the gnome cruft running. Start by turning that off. Then try inserting/removing audio discs, playing them with "cdplay". I'd expect that to be ok
Next try ripping an audio cd without all the gnome crud loaded. If that works (it may or may not) then its practical to try and pin down the bug and see if its error handling (the locking patterns all changed in the base kernel recently hence all those new PIIX error reports) or something else.

Then you'd expect to see "drive confused" methods. It could be IRQ related - missing IRQ might do it although I'd expect that to cause crashes during probe if we got extra IRQs (because the code to handle it was removed from the base kernel even though it is required).
Another thing that will do this is if you bomb the drive with commands from somewhere (say GNOME) or crash the firmware, which is why you need to isolate all the gnome gunge for testing, and if that makes the difference see if its a kernel or higher level change and if so what its doing that causes problems.
