dmesg output when radeon.audio=0

lspci output
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.

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