Public bug reported: Symptoms: Xorg freezes completely. Audio kept going for a while but then stopped too. Mouse cursor is the only thing I can control on the screen. ctrl+alt+f1-7 don't seem to work.
What I was doing at the time: Watching a youtube video and trying to connect a bluetooth gamepad. Report was gathered by ssh'ing from another machine. I can see that the Xorg.log contains a backtrace for the crash.
