Bug#837809: [drm:si_dpm_set_power_state [radeon]] *ERROR* si_restrict_performance_levels_before_s

[Heinrich Schuchardt <xypron.glpk@gmx.de>]

The message still occurs with Stretch kernel 4.9.0-3-amd64.

The message is created in drivers/gpu/drm/radeon/si_dpm.c
if si_restrict_performance_levels_before_switch fails.

My graphics adapter is
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Cape Verde XT [Radeon HD 7770/8760 / R7 250X] (prog-if 00 [VGA
controller])

xset dpms force standby
works fine on my system.
