(Perhaps) new Intel ICH sound issue

Hi,

I've just read some of the intel ich3 sound threads, but I have a
slightly different problem here.
Most people have had problems with IO mapping, but this device here
shows:

pcm0: <Intel 82801CA(ICH3)> port 0xe100-0xe13f,0xe100-0xe0ff irq4 at
device 31.5 on pci0
pcm0: unable to map interrupt
device_probe_and_attach: pcm attach returned 6

So it seems the interrupt causes the problem, not the IOs.
(By the way, I think irq4 is very unusual for a sound device, isn't
it?)

The system is a 4.6-STABLE, built this morning.

Has somebody got similar problems? Perhaps an idea how to fix?

Regards,
Riggs
