I also thought that the GPU might simply overheat but sensors told it has 60°C which should be fine. Kernel in use: 4.0.4 with patches (see https://bugzilla.kernel.org/show_bug.cgi?id=99041 ) 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. Does this patch fix it? http://cgit.freedesktop.org/mesa/mesa/commit/?id=d3c08309abd17b6e0d466b677af57e3cc74b0e00 Looks good. Thanks to you and the hw people. I was too fast on this, it's still there. This might help: https://cgit.freedesktop.org/mesa/mesa/commit/?id=d4d9ec55c589156df4edc227a86b4a8c41048d58 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 HyperZ hangs on big GPU. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 119002 [details] 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.
