--- Comment #6 from Brian Candler <b.candler at pobox.com> ---
FWIW, I have just started seeing this same error on a NUC DN2820 (which is bay
trail) after upgrading it from Debian Jessie to Ubuntu Xenial.

I have two of these NUCs, and only one showed the problem. It doesn't happen on
*every* boot but is fairly common. Unfortunately it is not writing the dmesg to
disk, but I do see hda_codec_runtime_suspend and rpm_callback in the backtrace.

Both machines have the latest BIOS (0053)

On a hunch, I went into the BIOS settings and reset them to defaults. After
three further shutdown / restart cycles I have not yet seen the problem recur.
