Hi,
I have recently added a Radeon HD4670 to one of my older PCs, and have noticed
that it has IRQ trouble when I try to enable the HDMI audio:
irq 17: nobody cared (try booting with the "irqpoll" option)
Pid: 0, comm: swapper/0 Not tainted 3.5.3 #2

This is frequently followed by KMS trouble too:

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

No, because wouldn't "irqpoll" have forced polling for every IRQ on the box? I need to avoid polling on the video card's IRQ because it noticeably impacts the responsiveness. (I assume that the kernel switches to polling the device instead when it disables the IRQ anyway).
I didn't try "pci=nocrs" because I didn't know about it. I can try that tonight.
Cheers,
Chris

No, you misunderstand.

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

Actually, it turns out that booting with "irqpoll=1" simply means that this problem takes longer to happen:
irq 17: nobody cared (try booting with the "irqpoll" option)
