[amdgpu][CIK] drm-next-4.9-wip - piglit test - max-texture-size - GPU deadlock

[Shawn Starr]

When I try to run piglit, I get a GPU deadlock running max-texture-size, 

Test: spec/!opengl 1.1/max-texture-size

I will begin bisecting kernel driver, but if anyone has some tips on likely 
commits I can test further.

Thanks,
Shawn
