Public bug reported:
I've had this problem for a while now. This doesn't always happen but
when I resume my machine from being suspended my networking doesn't seem
to work. I had a look through the processes list and I found that
pulseaudio was in the 'uninterruptable' state and the waiting channel
says 'usb_start_wait_urb'.
When I kill pulseaudio, the sound indicator disappears and the
networking functionality is restored, however pulseaudio is still sat in
the same state it was. I can't use programs that use sound (i.e. Totem,
Flash in web browser) as they just hang and I can't kill pulseaudio
properly in order to try and relaunch it. The only way I can fix the
issue is to restart my machine.
