Comment 1 Rafał Miłecki 2010-11-02 02:38:46 UTC 
Please try newer kernel and /sys/class/drm/card0/device/power_method
Comment 2 Timothy Arceri 2013-07-09 00:07:12 UTC 
Marking as invalid as the old dynamic power code is made obsolete by the new DPM code coming in the 3.11 kernal. 

Also the reporter never retested with a newer kernal after the initial report.
