<pre>There is/are a reproducible GPU lockup in Amnesia: Dark Descent video game on
Linux x86-64. Often it occurs when looking at certain doors in the levels. I
find that using VT-switch helps to recover the GPU in a reasonable timeframe to
a somewhat usable state. I do experience some jerkiness though after the stall
recovery.
Radeon 6750M
3.8.0-rc5
Everything else taken from xorg-edgers ppa
I'm happy to investigate this issue further.
