Hi Mauro,

3) From syslog:
These lines repeat, no matter what firmware,

And it finishes loading with this line:

<snip>

Mar 27 16:25:49 ubuntu kernel: [  137.252503] xc2028 2-0061: Error on

line 1080: -5
<snip>

After the first moment where tuner-xc2028 returns a negative value, it stops receiving later commands. this explains the error on line 1080. On USB devices, it only recovers after unplugging/replugging it. I'm not sure if just removing saa7134 and reinserting will revive the tuner.

I did a small change on the enclosed patch. Hopefully, this way, the tuner will reborn. Otherwise, you may need to reboot the machine.

Quoted 2 lines

And by the way, many, many thanks for helping while you're very busy!

You're welcome.

Cheers,
Mauro
