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

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.
