There are changes to > dvb_ca_en50221.c > > Jurgen > did you get it to work? i got a dvbsky T980C too for dvb-t2 reception and so far the only drivers that have worked at all is the ones from dvbsky directly. i was very happy when i noticed that recent kernels have support for it built in but unfortunately only the modules and firmware loads but then nothing actually works. i use mythtv and it complains a lot about the signal, running femon also produces lots of errors. so i had to switch back to kernel 4.0.4 with mediabuild from dvbsky. if there were any other dvb-t2 card with ci support that had better drivers i would change right away. one problem i have with the mediabuilt from dvbsky is that at boot the cam never works and i have to first tune a channel, then remove and reinstert the cam to get it to work. without that nothing works. and finally a problem i ran into when i tried mediabuilt from linuxtv.org. fedora uses kernel modules with .ko.xz extension so when you install the mediabuilt modulels you get one modulename.ko and one modulename.ko.xz before a make install from mediabuild overwrote the needed modules. any advice on how to handle this now?
