Comment 30 for bug 533784

Im sorry, your patch also doesn't work for me -- i see the same error as Rafał now.
I hadn't checked before if the correct kernel module was loaded.

So now I have rebuilt and loaded the correct modules drm.ko and radeon.ko, and the problem is simply reproduceable by running glxgears for instance.

To help you debug I loaded the drm module with debug=1 and got the log which I will attach. Note: After loading this module produces a lot of debug messages, I skipped a lot of the standard messages in the beginning, and the log stops with the error, that appears when running glxgears (Nothing interesting happens after that ...).

If I can provide more infos, I would be glad to help.
