[Intel-gfx] chrome crashing the gpu on sandy bridge

[Andi Kleen]

Hi,

The current version of chrome reproducibly hangs the GPU on my 
sandy bridge system when using google maps. The GUI freezes
and I have to kill chrome from a console to recover.

Known problem? Crash dump is attached.

Kernel 3.15.1 (opensuse version)

google-chrome-stable-35.0.1916.153-1.x86_64

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Desktop 
OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.2.3
OpenGL core profile shading language version string: 1.40
