Hm, you change a bit too much in one go, so it's not visible
which part fo the changes causes the problem.

Anyway, I reviewed the changes between 2.6.0 and 2.6.1 in dvb-core
and dvb-ttpci and found nothing obvious. I did not look at the
saa7146 driver yet.
And I'm not yet convinced that the new sw section filter code
(dvb_dmx_swfilter_section_copy_dump()) causes the problem.
