Public bug reported:
When MythTV is recording a program the system will hang part way through
the program. I can scan for channels (though I get inconsistent results
detecting them, but that may or may not be relevant here) and I can
watch live TV (though I haven't attempted watching for more than a
minute or two). Not sure if ubuntu-bug collected this, but here is the
kernel oops:
