GPU lockup crashing the system on Cayman with HyperZ

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.
