First off, I apologize if I'm reporting this bug to the wrong list or in the wrong manner; I have never done this before.
I've got a Skylake system (kernel 4.3.3-2-ARCH) using Pulseaudio and ALSA which uses a FiiO E10k Olympus 2 (external DAC/AMP) as the soundcard. Very seldom the system will fall to it's knees and ultimately hang, requiring a hard reboot. Checking the system logs gives an error and a dump from alsa-util.c, which is attached to this mail.
The error message from PA is fairly normal (PA is chatty and grumbling), so I guess it's a red herring, and no direct culprit of the hang.

I'm unsure if there is anymore info that you would need. If more is required, please, do ask.
