All I know of this crash is that all of a sudden my touchpad stopped working. Dell XPS M1330.

Waited a minute or so, plugged in a usb mouse, and all of a sudden it started working and the crash report came up. Nice recovery, good engineering for it to
1. Detect there was a crash
2. Recover

But still want the problem fixed.
