Function snd_pcm_period_elapsed() is part of sequence servicing HDAudio stream IRQs. It's called under Global Interrupt Enable (GIE) disabled - no HDAudio interrupts will be raised. At the same time, the function may end up calling __snd_pcm_xrun() or snd_pcm_drain_done(). On the avs-driver side, this translates to IPCs and as GIE is disabled, these will never complete successfully. Improve system stability by scheduling stream-IRQ handling in a separate thread.
