I've also just hit what seems to be the same panic in 3.17-rc1 (ignore the 1 local patch, it's an unrelated change in a comment) twice in less than 1 hour. Hitting this twice in a short amount of time seems to be proof that the 3.17 merge window made it trigger more often. Both times I was running a grep over a Firefox build tree which was taking a long time.
The stacktraces are slightly different but both have the "cancel timer from a timer, followed by nmi" pattern.
