I am not sure it is the same issue. But I am also observing some similar logs on RV730 (pci=1002:949f):

I'm using a Radeon HD 6870. This does not happen with other video players (totem, mpv). Tested with different video codecs and different window managers (gnome- shell, metacity). When VLC starts, the following message is printed to dmesg: [ 102.379520] [drm:btc_dpm_set_power_state [radeon]] *ERROR* rv770_restrict_performance_levels_before_switch failed This is not the case with Totem.
