you need more debug info to find out what happen
Enable basic debugging and dump stack, check hardware pointer on the period update
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa/HD-Audio.txt
how about enable_msi=0 ?
if it don't help, you need to file bug report at
