Ok, things look much cleaner(greener) on last run after I rebased on
top of a more recent drm-next.

https://intel-gfx-ci.01.org/tree/drm-intel-next-fixes/shards.html

My only concern right now is this one:

https://intel-gfx-ci.01.org/tree/drm-intel-next-fixes/CI_DINF_97/shard-kbl5/igt@gem_softpin@noreloc-s3.html

<7>[ 256.521580] [IGT] gem_softpin: starting subtest noreloc-S3
<7>[ 256.561583] [drm:gmbus_xfer [i915]] GMBUS [i915 gmbus dpc] timed
out, falling back to bit banging on pin 4
<7>[ 256.564321] [drm:drm_dp_dual_mode_detect] DP dual mode HDMI ID: (err -6)
<7>[ 256.564326] [drm:drm_helper_hpd_irq_event]
[CONNECTOR:70:HDMI-A-1] status updated from disconnected to
disconnected
�������������������������������������������

Could this be caused by?:
