--- Comment #4 from Darius Spitznagel <d.spitznagel at goodbytez.de> ---
Today I tested the apitrace on an weak Broadwell...

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Broadwell GT1 
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.0
(git-49a612d158)
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.3.0 (git-49a612d158)
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 17.3.0 (git-49a612d158)
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
OpenGL ES profile extensions:

There I had the same errors on replay but "NO GPU hangs" and the trace was
"rendered correctly".

So it's definitely a Haswell problem.

On both systems I have tested the trace with Kernel 4.9.68.
