what's the status on this? maybe a timing error? 
FYI, this is the commit: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commit;h=b16d9acbdb97452d1418420e069acf7381ef10bb
Comment 3 Alex Deucher 2010-02-17 07:43:54 UTC 
Is this still an issue with a newer kernel? drm-radeon-testing or 2.6.33rc8?
Comment 4 Florian Scandella 2010-02-17 11:13:23 UTC 
i'm using 2.6.32.8 + drm-radeon-testing atm.

will try with 33rc8 soon ...
Comment 5 Florian Scandella 2010-02-17 11:17:41 UTC
