Haha, thanks everyone.

Basically, there is some kind of kernel bug that causes my system to
lock up when I try to record /dev/dsp or alsa:adevice=alsa_device_id.

Is there any way to record from the default PulseAudio Sink?
Currently, I am simultaneously using parec to record the USB mic and
mencoder to record the capture device although it is quite sub-optimal
since there a *lot* of buffer underruns on the audio and the audio and
video are almost always out-of-sync.

Sam,
