Comme= nt # 15 on bug 11198= 7 from Witold Baryluk= 
Setting

echo high > power_dpm_force_performance_level

didn't help. It is set to high (verified by reading back from sysfs).

gpu_busy_percent is showing me 100 all the time, and sometimes jumps a litt=
le
lower, maybe 87, 95, then back to 100.

Despite all of this the GPU frequency is slowly and gradually dropping down,
until it reaches the lowest frequency and then jumps back to maximum.

It does look like a bug to me...
