2) hdaudio doesn't work on a regular NetBSD installation under qemu (and probably virtualbox too, though I didn't test with virtualbox)
Just FTR, I had trouble with auich(8) + Rump + Linux-UIO not propagating interrupts on Virtualbox due to shared IRQs. I suspect it might be a Virtualbox bug, as I couldn't reproduce the problem anywhere other than Vbox, and I didn't investigate further as I found a simple workaround (attached, maybe someone will find it useful). -- Robert Millan
