           Summary: ATI RV670 [Radeon HD 3870] Ioquake games causes GPU
                    lockup (waiting for 0x00003039 last fence id

kern.log

Tested and reproducible with Urban Terror, Warsow, and World of Padman.  Used
phoronix test suite, and at some point during the run of each game, it would
either freeze or eventually display weird output to the screen (attached). 

Occasionally a VT switch would let the game "appear" again.  Other times you
can hear the sound of the game continue.

I am using the 3.4 kernel and drivers/X, etc from Xorg Edgers PPA, which for
the ati driver would be 6.14.99+git20120525.b1e9c308 and mesa is     
8.1~git20120530.ff3eef1a.

You should be able to reproduce this by:
Installing phoronix test suite
(http://www.phoronix-test-suite.com/?k=downloads)
and then running: phoronix-test-suite benchmark urbanterror
(or warsow or padman)
