oops with 2.6.12-rc2

[Narayan Desai <desai@mcs.anl.gov>]

I got the following oops with 2.6.12-rc2. It occurred when I unplugged
a usb audio device while xmms (presumably) had it opened. I
have managed to do this successfully with the xmms closed. Once this
oops occurs, my keyboard is dead, and a reboot is required. The system
isn't hung, and oddly enough, the mouse still works.
