Comment 3 Takashi Iwai 2016-09-07 15:33:41 UTC
Could you report rather to upstream, e.g. bugzilla.kernel.org?  It'll be more help there.  Thanks.
Comment 4 Takashi Iwai 2016-11-25 09:21:58 UTC
Minchan Kim submitted a few fix patches, and I'm building a test kernel with these patches in OBS home:tiwai:bnc997574 repo.  Once when the package build finishes, it'll appear at
  http://download.opensuse.org/repositories/home:/tiwai:/bnc997574/standard/

Could you test the kernel and confirm whether the issue is fixed there?  Thanks.
