dmesg output when radeon.audio=1

I have recently added a HD4670 AGP to one of my older machines, and I am
noticing problems with the HDMI audio device. Specifically:

irq 17: nobody cared (try booting with the "irqpoll" option)
Pid: 0, comm: swapper/0 Not tainted 3.5.3 #2
Call Trace:

Disabling IRQ #17

This is with radeon.audio=0. With radeon.audio=1, the KMS IRQ has similar
problem and is also disabled.

According to alsamixer, my HD4670 only has a S/PDIF playback device. However,
my HD4890 has both S/PDIF and PCM playback devices. I don't know whether this
is significant.

Apparently, the KMS IRQ can fail even when radeon.audio=0. So it looks like the
audio IRQ always fails and sometimes takes the KMS IRQ with it - seemingly at
random.

Booting with "irqpoll=1" doesn't fix the problem; it simply no longer happens
at boot time:
