Bug #1551041 affects my hp xw8400 workstation when running 32-bit *Xenial*. Raymond (superquad-vortex2) has helped me identify the problem, and he found, that it is probably caused by what you describe in the following link,

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/core/pcm_lib.c?id=00d90154404ae6218730068d25bf2faad3186631

that is *this bug*

ALSA: pcm: 'BUG:' message unnecessarily triggers kerneloops
BugLink: http://bugs.launchpad.net/bugs/1305480

The kerneloops-daemon scans dmesg for common crash signatures, among which is 'BUG:'. The message emitted by the PCM library is really a warning, so the most expedient thing to do seems to be to change the string.
