Comment # 2 on bug 93762 from Nicolai H�hnle

Thanks for the report. Did the messages

[43513.525167] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_set_sw_state
failed
[43982.380508] [drm:si_dpm_set_power_state [radeon]] *ERROR*
si_restrict_performance_levels_before_switch failed

occur at the same time as the stutter? That would point at a kernel problem.
