The fix with shuting down the network interface is confirmed. I experience the same problem with haning on alsa shutdown on a hp laptop with a usb 3g modem. But if i disconnect it using the network manager menu option ( below the list of available networks when left clicking on the network manager icon ) prior to shuting down the laptop it shuts down normally.
