[Bug 105064] GPU Hang with single-channel RAM configuration

--- Comment #19 from Clayton Craft <clayton.a.craft at intel.com> ---
Chris, I had to build 4.16 in order for your patch to apply (it doesn't apply
to 4.15, which was used originally to hit this issue).

But I cannot reproduce the issue on a vanilla 4.16 kernel *without* your patch.
10 full runs of piglit did *not* cause a gpu hang on a skl system running with
single channel RAM config. If I roll back to 4.15, I can reproduce the gpu hang
on the same system after 1-2 piglit runs.

Based on my testing, it seems like this issue is magically resolved by some
change in 4.16 from 4.15 (where the issue is hit).
