dmesg part 1 (png file)
Reproduced with Left 4 Dead 2, Distance and Metro 2033 Redux.
First the screen either freezes (Distance) or shows garbage, looks like many
small brown rectangles on the screen (Left 4 Dead 2, Metro 2033 Redux), then,
after around 30 seconds, the whole system freezes (keyboard/mouse doesn't
react, ssh connections drop, finally watchdog kicks in and reboots the system).
In between the 30 seconds I was able to grab some data via ssh. Screenshots
attached.
This is on a HD 6950.

radeontop output while the screen shows garbage (Metro 2033 Redux)
I also thought that the GPU might simply overheat but sensors = told it has 60=C2=B0C which should be fine. Kernel in use: 4.0.4 with patches (see https://bug= zilla.kernel.org/show_bug.cgi?id=3D99041 )
Forgot to say: It's very random. Sometimes it happens after 20 minutes of gameplay, sometimes I can play for hours without problems.

Seems to be a problem with HyperZ. R600_DEBUG=nohyperz looks like a workaround.

This might help: https://cgit.freedesktop.org/mesa/mesa/commit= /?id=3Dd4d9ec55c589156df4edc227a86b4a8c41048d58 Although it's an unrelated feature, it changes the allocation function from pipe_buffer_create to r600_aligned_buffer_create. I believe that can fix Hy= perZ hangs on big GPU.
