Public bug reported:
Hi.
I'm running Ubuntu MATE 16.04 running kernel `4.4.0-128-generic`.
Since applying updates this morning I'm now unable to shut my machine
down cleanly. If I shut down or restart, the error
`snd_hda_codec_realtek hdaudioC0D0: unable to sync register` is output 3
times and the machine doesn't power down. I have to finish the shutdown
manually by holding the power button.
Wasn't sure which debug steps to follow for this error, but this is the
corresponding extract from `/var/log/kern.log`:
```

I made the report using `ubuntu-bug linux` so hopefully this will
provide the necessary debug info. If I need to post more info, let me
know what you need.
Thanks
