The recent workaround for the wild interrupts in commit c1f0616124c4 ("ALSA: intel8x0: Don't update period unless prepared") leaded to a regression, causing the interrupt storm during ac97 clock measurement at the driver probe. We need to handle the interrupt while the clock measurement as well as the proper PCM streams.
