Comm= ent # 122 on bug 10995= 5 from haro41@gmx.de 
In my experience, this issue is related to mclk switching and =
it affects the
lowest mclk level only.

So you guy's can save a lot of power, if you, insteed of switching to highe=
st
gfxlevel or to disable vsync, just disable the lowest mclk level by:

echo "manual" > /sys/class/drm/card0/device/power_dpm_force_pe=
rformance_level
echo "1 2 3" > /sys/class/drm/card0/device/pp_dpm_mclk

If you are building your kernel locally, look in this thread for a driver c=
ode
modification that works, without disabling the lowest mclk level (saves a f=
ew
watt on idle).
