On a Thinkpad W520 using the Intel GPU, playing Zandronum (gzdoom) with the (graphically intensive) Brutal Doom mod, every 5-15 minutes, a GPU hang occurs.
Usually, the GPU gets reset properly. Sometimes, however, it freezes the entire system.
Linux Kernel 4.4.0, 64bit, mesa-11.0.6, xorg-server-1.17.4, xf86-video-intel-2.99.917. No i915 cmdline parameters are in use. TearFree is used.
The hang was also observed on kernel 4.1.12.

I am capable of testing kernel and userspace patches.
