--- Comment #4 from Jim Paris <jim at jtan.com> ---
I have the exact same system (slightly older BIOS version) and I'm seeing the
same lockup, which occurred while idling over the weekend.  Seems to be
stemming from nvkm_fantog_update.

This is 4.2-rc6.  I also saw lockups on 4.1.0 which I'm guessing were the same
cause, but I wasn't able to get any logs from those.  3.13 was working fine.
