Re: [alsa-devel] snd-intel-hda: screaming IRQ with 3.5.3 kernel (HDMI)

----- Original Message -----

Did you try any workaround boot options such as irqpoll, pci=nocrs or whatever?

OK, the "irqpoll=1" option does help here. Although this message is obviously scary:

Misrouted IRQ fixup and polling support enabled This may significantly impact system performance

And the "pci=nocrs" option does Really Bad Things to the display at boot-time.

So what is "irqpoll" actually doing, please? Is it just a temporary workaround for a driver bug?

Thanks, Chris
