   This should be fixed with combination of latest SOF and i915 driver fixes (all patches in #1155 ).

   This still occurs with latest #1155 code. It seems the problem is hit in snd-hda-codec-hdmi resume code. No rootcause yet. This happens only on ICL.

   pm_test run with "core" reports following warning from i915. Not known yet why this does not get triggered with hdac-hdmi:

   [ 386.226725] i915 raw-wakerefs=1 wakelocks=1 on cleanup

   This is fixed now, both i915 and SOF kernel patches merged.
