retested with media_tree at commit: 13f6e8887a1f61764a05a3348476d38071201f08
this is the most recent one that i bisected before that doesn't result
in module load problems.
with my patch to add the new revision of the 4650 usb device and above
commit plus your proposed change to si2168.c did not produce any
different result.
still problems tuning dvbt2 channels.
i also tested my updated tuning file for dvbv5-scan with my other usb stick:
Bus 001 Device 004: ID 2013:024f PCTV Systems nanoStick T2 290e
to confirm the scanning input file was good and it was.
the pctv stick can properly tune the t2 muxes.

Hi Torbjörn,
I connected my old v1 CT2-4650CI to my test PC and indeed, it seems

Perfect.
Looks like i have some more testing to do in the next few days.
something else, when testing my 4650 card i cant get it to tune
properly to
dvb-t2 muxes.
but i'm not yet sure if this is a driver issue or if i made a
mistake with
the tuning parameters since the file i use that came with the dvbv5
programs
was missing the t2 mux so i had to put that one in manually.
so more testing is needed first and with your patch for the T980C
card i can
probably test both things at the same time.

Hi all,
Found the issue and submitted a patch.
The I2C buses for T980C/T2-4500CI were crossed when CI registration
was moved to its own function.

this ci problem is the reason i decided to buy the CT2-4650 usb based
device
instead.
but the 4650 was a slightly newer revision needing a patch i
submitted
earlier.
and also this 4650 device does not have auto switching between
dvb-t and
t2
like the dvbsky card have, so i also need an updated version of
mythtv.
my long term wish is to not have to patch things or build custom
kernels
or
modules.
so anything done to improve the dvbsky card or the 4650 is much
appreciated.

This is indeed a too complex function, with lots of stuff

Breaking this into two functions makes it a little bit
less hairy.

Hi Jürgen,
Did you get anywhere with this?
I have a clone of your card and was just starting to look at this
issue. Kernel 3.19 seems to work ok, but 4.3 not. Did you have any
time to try to pinpoint this more?
No, unfortunately not. I have spend a few hours adding printk's
but it
did not get me any closer what causes the issue. This really needs
investigation from someone who is more familiar with linux media.
Last thing I tried was the latest (semi open) drivers from
dvbsky on a
4.3 kernel. Here the CI and CAM registered successfully.

the CAM

The normal 'CAM detected and initialised' messages to do show

I am not sure what changed in the recent kernels, what is

Retest. I've isolated one T980C on another PC with kernel
4.1.5, still the same 'Invalid PC card inserted :(' message.
Even after installed today's media_build from git no
improvement.
Any hints where to start looking would be appreciated!
cimax2.c|h do not seem to have changed. There are changes to
dvb_ca_en50221.c
Jurgen
did you get it to work?
No, it needs a thorough debug session. So far no one seems
able to
help...
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?
