Description Piero Finizio 2012-12-01 11:25:52 UTC 
With last graphics drivers from Git-da7029d on ATI RV530 (X1700) all the 3D applications with "radeon: Acquired Hyper-Z", as Second Life, Racer, Quake III demo have blank screen and in their respective logs these lines appear:
...
radeon: The kernel rejected CS, see dmesg for more information.
radeon: The kernel rejected CS, see dmesg for more information.
radeon: The kernel rejected CS, see dmesg for more information.

With dmesg command I obtain:

Comment 1 Alex Deucher 2012-12-01 14:09:36 UTC 
What kernel are you using?  A newer kernel should fix the issue.
Comment 2 Tomasz P. 2012-12-01 17:48:47 UTC 
Simlilar issue with radeon 9600 agp.
I use kernel 3.6.8

In logs:
dmesg: Forbidden register 0x4F34 in cs at 40 (val=00000640)
radeon_cs_ib_chunk] *ERROR* Invalid command stream !

triggered by opera-next (HA,webgl enabled), just scroll down any page and it hangs.
Comment 3 Tomasz P. 2012-12-01 17:50:45 UTC 
I just check that even glxgears display static picture and it hangs also.
Comment 4 Piero Finizio 2012-12-01 18:54:27 UTC 
My kernel is 3.6.8-1.fc17.i686
If I don't use HyperZ all is right... as well with graphics drivers from (git-e7177e3). 
Is it inherent in the commit "r300g: fix comparison of hyperz flush time", perhaps?
Comment 5 Marek Olšák 2012-12-01 20:47:21 UTC 
Fixed by commit 3e3a586236815970b5eab36697e221e9a72542d6.
