--- Comment #6 from Libin Yang <libin.yang at intel.com> ---
I did the test on my SKL with latest nightly kernel doing the s3 stress test.
But I can't reproduce this issue.

If it is the i915_power_refcount issue, is there any possibility that the below
will happen:
1. runtime_resume is called (link_power_control is not set so far)
2. set the codec->core.link_power_control = 1 in hdmi audio driver
3. runtime_suspend is called
