Followup: I also get the following messages spewed to dmesg every single frame,
regardless if I'm using Mesa 7.10.2 or git master or anything in between. I'm
not sure if this is related to the problem or just noise. But I suspect that
it's unrelated, because I don't experience any symptoms of failure (crash, OOM)
with 7.10.2, and the messages still get spewed. The frequency is about once
every frame, or a bit more often. Maybe as frequently as once per kernel tick
(~1000 Hz timer).

[  564.159042] DRHD: handling fault status reg 2
[  564.159248] DMAR:[DMA Write] Request device [04:00.0] fault addr 44bc0000 
[  564.159249] DMAR:[fault reason 05] PTE Write access is not set

The DRHD line appears less frequently, but the DMAR lines are always grouped
together like that. I tried running other GL apps and it doesn't happen there.
