--- Comment #4 from john.stultz at linaro.org ---
Also, using the 15.10 live-cd, I've triggered the same problem. Which seems
odd, as I don't recall seeing it when I originally installed the machine.

I've also run memcheck and didn't find any issues there, so it doesn't seem
like the memory in the system has suddenly gone bad.

Using i915.enable_rc6=0 doesn't seem to solve the issue. Nor
intel_pstate=disable.

Sometimes those allow the system to run for longer, w/o the graphical
corruption, but when a hang occurs its a hard hang, and I can't recover.
