Bug Description:
In UXA mode, with tiling on ut2004-demo will hang at somewhere but you can still hear its sound is playing and finally got a score of 20 points. With tiling off, it will not hang but has a very bad performance scored only 3 or 4 points.    

Reproduce Steps:
1. xinit&
2. run ut2004

In UXA with tiling on, it still freezes X until the demo run over. With the following configuration:

Does this happen with KMS?
Comment 4 Gordon Jin 2009-06-03 16:36:47 UTC
Jian, please answer.

And attach gpu-dump.
Comment 5 zhao jian 2009-06-04 00:56:57 UTC
Now with the newest code, it works well both in KMS and UMS.  Its configuration is :
