See the thread ([linux-dvb] TDA9887 Problem - FusionHDTV5 Lite)

I'm having the exact same problem which appears to be a bug introduced
during code development for a new tuner (or something like that). In
that thread, Mike Krufky posted a temporary patch for dvb-bt8xx users,
but I believe you won't benefit as you have a different chip.

Aha!  That certainly explains it...  Thank you, Hermann.

I'll wait on Hartmut for a fix.... Until then, I'll refer my testers to
my patch earlier in the thread.  Hopefully that should temporarily solve it.
