           Summary: 3D applications have blank screen with "export

          Severity: normal
    Classification: Unclassified

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:
...

What kernel are you using?  A newer kernel should fix the issue.

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.

I just check that even glxgears display static picture and it hangs also.

--- Comment #4 from Piero Finizio <andabata12@yahoo.it> ---
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?
