The GPU Hang is still happening.

GNU/Linux

OpenGL version string: 3.0 Mesa 17.1.1

Intel HD 520 Graphics (Skylake GT2)

xonotic-sdl [1467], reason: Hang on render ring, action: reset

I've done some ApiTrace attemps and recorded while the GPU Hang occurs. After
the hang the application closes immediately and ApiTrace stops recording.

The .trace files can be found here:

application: xonotic-glx
md5: 10f4481e7a7e49c2ed79aae97c518b4e
size: 1824170391 bytes / 1,8 GB
link: https://dl.terminal.run/apitrace/xonotic-glx.trace
info: gpu hang happened at the end, the freeze was where the trace ends

application: minetest
md5: af2a7d60f1955ff6d45cc5316c31ad9a
size: 656264517 bytes / 656,3 MB
link: https://dl.terminal.run/apitrace/minetest.trace
info: gpu hang happened at the end, the freeze was where the trace ends

Freeze happens only if the notebook is connected to the charger. No problems in
battery mode but low FPS etc.
RC6 is off, but the problem is the same with RC6 on.
