Hi
Running -current on a Lenovo G500 (dmesg below) recent snaps give the
following error messages on boot:
Jun 18 22:11:37 alegreya /bsd: drm:pid80480:ivb_set_fifo_underrun_reporting *ERR
OR* [drm] *ERROR* uncleared fifo underrun on pipe A
Jun 18 22:11:37 alegreya /bsd: drm:pid80480:intel_cpu_fifo_underrun_irq_handler
*ERROR* [drm] *ERROR* CPU pipe A FIFO underrun
Jun 18 22:11:37 alegreya /bsd: drm:pid80480:cpt_set_fifo_underrun_reporting
*ERROR* [drm] *ERROR* uncleared pch fifo underrun on pch transcoder A
Jun 18 22:11:37 alegreya /bsd: drm:pid80480:intel_pch_fifo_underrun_irq_handler
*ERROR* [drm] *ERROR* PCH transcoder A FIFO underrun
Doesn't seem to be affecting performance and, to date, there are no
further errors reported after boot. I'm guessing this is related to
recent inteldrm changes.
