Hello,
I have compile it (I hope) the more right way now :-)
The patch saved as aaa.patch in media_build/backports
and added lines to media_build/backports/backports.txt:
----
[3.2.0]
add aaa.patch
----
Now dmesg looks like:

First I have thing the problem is gone: It has run OK over 20 minutes
(before it goes down mostly in <10 min on CH59).
But - unfortunately after cca 25 min it has go down again :-(

So - maybe is it little better, but the problem persist.
Any chance to solve it in dvb driver ?
I have tested (with the old driver) - that it helps to CTRL+C the:
tzap -r -c /etc/channels.conf "Prima ZOOM"
And then run it again. (It was not necessary to switch to another freq.
and back, as I wrote before).
Unfortunately it damages for a while the recording (file.ts).
Is there another way how to "re-tune" (re-zap) without break
recording/viewing ?
I could then re-tune e.g. every 5 minutes and it could solve the problem.
Could not that be done in driver itself ?
Thanks.

Hello,
unfortunately I do not understand development, patching, compiling things.
I have try it but I need more help.
I have done:
git clone --depth=1 git://linuxtv.org/media_build.git
cd media_build
./build
it downloads and builds all. At begin of compiling I had stop it.
Then I did manual change of
./media_build/linux/drivers/media/usb/dvb-usb-v2/af9035.c

But now I do not know how to "restart" build process.
Just
make
from media_build directory.
I have try:
cd /tmp/media_build/linux
make
It had compiled *. and *.ko files.
you need to run
/sbin/depmod -a
and reboot
it best to just run with su/sudo
make install
I have just tested all the single ids.
I am about to send a patch to add all the single tuner ids
to af9035 from it913x.
I haven't found any problems.
Regards
Malcolm
