latency 32 is quite low; this parameter effects how long the device
can hold onto the bus.  try
	setpci -s 02:01.0 latency_timer=80
and see whether it improves things.  I'm unclear on whether a bridged device
also needs the bridge's latency setting changed.

also low.  I'm guessing that your bios is tuned for desktop use - some audio
setups need low latency settings.
