[mythtv] mythbackend stops responding with HDPVR

[P S]

I received an HDPVR as a gift and have been holding onto it for a few
months waiting for Trunk to stabilize more.

It seems now is a good time to start experimenting with Trunk.  I am
running a non-production system based on mythbuntu 8.10 and compiled
trunk revision 20389.  I also compiled the v4l-dvb drivers for the
HDPVR rev 11485.

Everything seems to go fine: I load the HDPVR module, it shows up as
/dev/video0.  Run mythtv-setup, add the HDPVR an encoder, setup
scheduled direct, setup the input.  I schedule a bunch of HD recording
off a Directv and it records no problem.

I come back in a few hours to see that mythweb will not respond.  I
look at the backend log and all that seems to be running is the
autoexpire jobs.  I restart the backend and it will start recording
again, only to stop a few hours later again.

What seems to be happening is the HDPVR stops recording(the annoying
blue lights turns off) but mythtv thinks it is still recording.  After
the recording ends, the backend stops responding for the most part and
no future recording occur until the backend process is restarted.

I have already RMA'd the unit back to Hauppauge for this issue and the
replacement does the same thing.

I would like to issue a bug report, but, I'm not sure where to start
troubleshooting this issue, here is the backend log with standard
verbosity.  I can supply a more verbose log, but I'm not sure which
verbosity options to use.  There are no errors within the kern.log.
