            Bug ID: 92555
           Summary: GPU lockup crashing the system on Cayman
           Product: Mesa
           Version: 11.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: v10lator@myway.de
        QA Contact: dri-devel@lists.freedesktop.org

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.

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.

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.
