That's normal behaviour. dvb-usb-framework calls .pid_filter_ctrl(0) 
callback to ensure pid-filter is disabled. Those logs will not seen 
normally when debug-logs are disabled.

hmm, no idea. Sometimes I have also seen rather similar problems when 
switching channels but restarting Totem solves problem.

I did full band w_scan and it founds all muxes I can receive (4xDVB-T + 
1xDVB-H). I haven't tested Kaffeine.

For me it seems like tuner is not connected to GPIO pin at all. I will 
wait someone else, Thomas?, will test. Testing this (af9015_aver_a850_2) 
tree is enough if it works:
