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.

Build date and platform:
    Build date of all components: 01/18/2014
    Linux kernel version: 3.13-rc8 x86_64
    Mesa: git (566e0ddfd01dbadd75462fed5a3f141b9f494028)
    LLVM: 3.5-svn (commit 199570)

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".
