dmesg output related to the GPU stall.
Overview:
The game "Team Fortress 2" causes the GPU to stall randomly. The stalls
sometimes resolve by themselves after ~1 min, but will occur again rapidly.
Steps to reproduce:
1) Install "Team Fortress 2" through Steam (
http://store.steampowered.com/app/440/ ).
2) Start the game, join a map.
3) Play until the GPU hangs.
4) Optionally: wait until GPU recovers.
Actual results:
Frequent GPU stalls while playing Team Fortress 2. Sometimes video output
is restored after ~1 min.
Expected results:
No stalls.

Additional information:
I am running on a Radeon HD 7970 with DVI output at 2560x1440. Dynamic
power management is enabled. Disabling Hi-Z does not alleviate the problem. The
output of "dmesg 'drm\|radeon'" has been added as an attachment. I could not
reproduce the issue (yet) in another Source engine title, "Left 4 Dead 2".
