Public bug reported:

My Hauppauge Nova-HD-S2 worked perfectly in 11.04. I upgraded to 11.10
and now kern.log is filled with hundreds of errors per second when Myth
Backend or scan try and use the card.

I have a second (DVB-T) card which uses the same driver and that card
works OK.

1. I upgraded to 11.10
2. I expected my Nova-HD-S2 to continue working in Mythtv.
3. I can't watch any channels on Freesat in MythTV. Mythfrontend starts going 
very slowly and I get hundreds of errors per second in /var/log/syslog and 
/var/log/kern.log. The files got to ~700MB each before I caught the problem.
