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. Pictures of the 2 stacktraces:
