<pre>I see two MST streams being restored during resume. The only issue I can spot
in the modeset for these is:
[ 50.162397] [drm:drm_dp_mst_allocate_vcpi] initing vcpi for 532 14
[ 50.162997] [drm:intel_mst_enable_dp] 1
[ 50.176764] [drm:drm_dp_check_act_status] failed to get ACT bit 1 after 30
retries
[ 50.176765] [drm:drm_dp_update_payload_part2] payload 0 1
and
[ 50.218921] [drm:intel_mst_pre_enable_dp] 1
[ 50.218922] [drm:drm_dp_mst_allocate_vcpi] initing vcpi for 387 10
[ 50.219535] [drm:intel_mst_enable_dp] 2
[ 50.233404] [drm:drm_dp_check_act_status] failed to get ACT bit 1 after 30
retries
[ 50.233405] [drm:drm_dp_update_payload_part2] payload 0 2
[ 50.233405] [drm:drm_dp_update_payload_part2] payload 1 1
Adding Dave. Any idea?</pre>
