Description Ernst Sjöstrand 2012-06-20 14:26:40 UTC

Hi,

I've been running with the following in my rc.local for a while:
echo dynpm > /sys/class/drm/card0/device/power_method

But when I tried a 3.5 kernel today I got a kernel panic as soon as dynpm was enabled!

Ubuntu kernel 3.5.0-1.1-generic
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Barts PRO [ATI Radeon HD 6800
