  • The last time I remember this happening I had Spaces enabled, and thinking there was an issue with the external monitor connected with Spaces enabled (I think the crash happened after the MBP went to sleep overnight, connected to power, and I woke it in the morning to have it go kerplooey) I disabled Spaces and it seemed to be more stable, as I didn't remember it happening for quite awhile.
