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

Disabling IRQ #17
This is with radeon.audio=0. With radeon.audio=1, the KMS IRQ has similar
problem and is also disabled.
