Decided to try 3.0-rc to see if it would be 3 for 3. It was. I booted with my magic mouse connected via an asus doggle supporting 2.1+EDR. When I started X it was not working so I powered it off and on. During the process it crashed. I got the following oops off my serial console (followed by a few more before it died).
