But maybe the issue I've reported is related to this other one. Maybe you remember that I reported a problem on the xc2028 tuner that was reloading all the firmwares each time a new frequency is tuned. As a consequence, the time to switch to a new channel was much higher that usual. I tracked down the problem to the fact that the xc2028 is put in power-off mode and then immediately woken-up each time Kaffeine sets a new frequency. I investigated the issue a bit deeper (enabling debugging also in the dvb-core) and this is what I discovered: [ 1635.878002] dvb_frontend_release [ 1635.878029] xc2028 9-0061: Putting xc2028/3028 into poweroff mode.

This strange behavior was introduced with the conversion of drivers to the DVBv5 API; before, the frontend was initialized just one time. This happens with all drivers: I reproduced the same issue with a stick using the as102 driver (which is completely different from the em28xx-dvb driver). Here is the relevant part of the log: [ 2339.647230] dvb_frontend_release [ 2339.656954] dvb_frontend_open [ 2339.665675] dvb_frontend_start [ 2339.665872] dvb_frontend_thread [ 2339.665878] DVB: initialising adapter 0 frontend 0 (Sky IT Digital Key (green led))...

I have no idea if this is a bug in Kaffeine that is triggered by the new DVBv3 emulation logic, or a bug in the emulation logic itself. Best regards, Gianluca
