Back on the same track again, I've managed to get a oops dump from the
DVD related oops I was having:

I'll try and see if I can get the same dump out of an untainted kernel
(non-vmware) and also while not using preempt. The same crash DOES
happen on same version less vmware and preempt as well.

Usually it would crash if I had a DVD in while logging into gnome2
(rawhide, everything up to date), but if I mount it manually after
logging in I can now catch the oops from dmesg/syslog.
