Well, I'd rather like to get to the bottom of this. Please
run 'ivtvctl -D479' as root to enable debugging and see if that turns
up anything interesting in the logs.
Are you also capturing VBI data in MythTV? (Check the MythTV setup) If
so, then turn that off and see if the lockup still happens.
If you make a whole bunch of small 1-minute recording, does that trigger
the bug as well? (Should reduce test time)

Hans
