Good point.  Most of the things I've found about kernel panic say it's
almost always a hardware problem.  I hope that's the case and it's not what
you're describing.

OTOH I just finished running 10 passes of memtest86+ and it found no
problems :-(  so if that's believable it's not a hardware problem in the
memory sticks.  I still can't find any way to test the video hardware in
linux.

About a week ago I was having problems with choppy audio because I did not
have the video playback profile set to use VDPAU.  Interestingly, when I
played back under that scenario, the audio was hosed but I did not have this
lockup problem--i.e. a recording would play all the way through.  So
something must be amiss in the hardware or software associated with VDPAU.
