Hi misc, following errors are derrived from dmesg (full dmesg below):
error: [drm:pid0:cpt_set_fifo_underrun_reporting] *ERROR* uncleared pch fifo underrun on pch transcoder A error: [drm:pid0:intel_pch_fifo_underrun_irq_handler] *ERROR* PCH transcoder A FIFO underrun Both with 6.2 MP and SP. These errors haven't been reported with 6.1-stable. Later on xconsole I get: error: [drm:pid49268:intel_pipe_update_start] *ERROR* Potential atomic update failure on pipe A PID search: $ ps ax | grep 49268 49268 ??
