I'm also using such a DVB-T board here in Berlin/ Germany, and can
confirm your problems. Reloading just dvb-ttpci resolves it.

I think I also had similar problems with Windows, but there it was in
most cases sufficient to restart the application - I don't know what the
application actually does with the hardware, though...

Cheers,
Juri
