Comment # 1 on bug 1191247 from Takashi Iwai

I'm building a kernel with a backport from the upstream commit that might be
relevant.  It's being built in OBS home:tiwai:bsc1191247 repo.  It'll be
available later (after an hour or so) at
  http://download.opensuse.org/repositories/home:/tiwai:/bsc1191247/standard/
Please give it a try later.

Note that it's an unofficial build, hence it won't boot with Secure Boot.
