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. When Firefox is started, or if Firefox had been running in the first place, a few seconds later it locks up: [ 157.157196] radeon 0000:01:00.0: ring 5 stalled for more than 10104msec [ 157.157212] radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000000003b7 last fence id 0x00000000000003bb on ring 5) [ 157.506657] radeon 0000:01:00.0: couldn't schedule ib [ 157.506746] [drm:radeon_uvd_suspend [radeon]] *ERROR* Error destroying UVD (-22)!
