System is becoming near-unusable. Problem was also present on 3.14.4. During boot I also get the 'pipe_off wait timed out' / 'failed to disable transcoder A' errors, which is not critical but hangs the system for a time -- Aug 4 13:51:09 tamarix kernel: [ 1.468677] [drm:ironlake_disable_pch_transcoder] *ERROR* failed to disable transcoder A Aug 4 13:51:09 tamarix kernel: [ 1.471229] [drm:cpt_set_fifo_underrun_reporting] *ERROR* uncleared pch fifo underrun on pch transcoder A Aug 4 13:51:09 tamarix kernel: [ 1.471229] [drm:cpt_serr_int_handler] *ERROR* PCH transcoder A FIFO underrun Aug 4 13:51:09 tamarix kernel: [ 1.476527] [drm:intel_dp_start_link_train] *ERROR* too many voltage retries, give up This is on DP, running at 2560x1440.
