Hmm, alright given the timing my suspicion would be a regression
introduced by either the xserver or mesa updates that occurred shortly
prior to this might have led to the freeze, but given that it seems to
have happened only once, it'll be very hard to narrow in on an actual
suspect.
Still, I've received a handful of other i965 gpu freeze regression
reports similar to this one. Except for #760054, the error codes vary a
bit so they're not perfect dupes. All hard to reproduce or one-time-
only, so debugging this lockup could be quite hard.
I think what I'm going to do for now is dupe these bug reports together
and forward a bug report upstream on the chance that they recognize the
issue.
