: auich skips interrupt processing if the device is currently inactive.

  I don't think that is the problem.  I hear sound for about 30
seconds, then sound and all network traffic stops.  A ifconfig down/up
restores networking.  If I play sound from an USB disk (uhci also uses
interrupt 11), access to the USB disk hangs and umount fails (even on
shutdown).  As an additional data point, I never had that problem with
iwi instead of wm.
