Problems with Linux drivers (Debian Jessie kernel 3.16.0-4)

Hello,

Could you get the media code from linuxtv.org?
and build this driver and install.
http://git.linuxtv.org/cgit.cgi/media_build.git/about/

*Subject:* Problems with Linux drivers (Debian Jessie kernel 3.16.0-4) Hi,

I reinstalled after updating my system with the Linux drivers for the dvbsky cards provided by your site (media_build-bst-14-141106).

Compiling with the build_x64.sh script was successfully and I could install the needed drivers via make install. After that the Conexant Systems CX23885 (DVBSKY S952) card works perfectly.

Unfortunately after installing the drivers my Philips Semiconductors SAA7146 (TT-Budget C-1501) card doesn't runs anymore - the card worked perfectly before installing the provided drivers from your page!

If got following error message in the kernel-log:

I think something went wrong with the provided driver packes or some drivers where overwritten, and some necessary not... I couldn't found any solution in the internet.

Here my relevant system-infos:

Could you provide me any help for a solution getting the SAA7146 (TT-Budget C-1501) card working again with the kernel 3.16.0-4? With the kernel 3.2.0-4-amd64 (with Debian wheezy) and the drivers media_build-bst-13-140526 I didn't had the problems... everything worked fine. Downgrading is no solution :-)

Attached the complete dmesg protocol.

Thanks a lot!

Hello Antti,

the guys from [email protected] told me to contact you because of my problems with the drivers for my DVBSKY S952.

I attached the whole conversation. Currently the main problem is if i use the current drivers via git(http://git.linuxtv.org/cgit.cgi/media_build.git/about/) my single TT-Budget card works fine. But the signal from the DVDBSky S952 is very
worse: Sync problems, bad SNR, drops on video and audio... If I use the driver dvbsky.net provides (media_build-bst-14-141106), the signal on booth tuners is fine - but then my TT-Budget doesn't works anymore (see end of this mail aka starting the conversation with [email protected]).

Do you have any ideas, how I could fix this problem? Before I updated my system (from Debian Wheezy with Kernel 3.2.0-4-amd64 everything was fine with both cards.

If you need more detailed information, please let me know, so I could provide them as soon as possible,

Thanks a lot and best wishes
Chris

with the drivers from linuxtv.org and the firmware provided by your site, both cards work.

But the DVBSky card (Montage M88DS3103) do now have a really bad SNR!TT-Budget C-1501 works as expected. See the output of femon - the signal of the DVBSky card was excellent with the drivers from you site... Any idea, what could cause the problem? TV signal provided by the DVBSky sometimes drops :-(

According to logs, everything seems to be fine. You could not compare statistics numbers between two drivers. SNR 0096 is 150DEC, which means 15dB, IIRC it was max chip could return for DVB-S.

No idea about sync etc. problems, are you sure about those? I am pretty sure it works rather well as I haven't got bug reports from PCTV 461e users which has that same demod + tuner.

Antti

I think something went wrong with the provided driver packes or some drivers where overwritten, and some necessary not... I couldn't found any solution in the internet.

Could you provide me any help for a solution getting the SAA7146 (TT-Budget C-1501) card working again with the kernel 3.16.0-4? With the kernel 3.2.0-4-amd64 (with Debian wheezy) and the drivers media_build-bst-13-140526 I didn't had the problems... everything worked fine. Downgrading is no solution :-)

Attached the complete dmesg protocol.

Thanks a lot!

Hello,

I yust checked the SNR Level the DVBSky-Card providing with the drivers from dvbsky.net (media_build-bst-14-141106):

# ./femon -a 0
using '/dev/dvb/adapter0/frontend0'
FE: Montage DS3103/TS2022 (SAT)
status 1f | signal 7323 | snr b064 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

# ./femon -a 1
using '/dev/dvb/adapter1/frontend0'
FE: Montage DS3103/TS2022 (SAT)
status 1f | signal 7a71 | snr 2a17 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

Looks "better" than with driver from linuxtv.org via git. And I don't have any sync problems or video / audio drops.

I currently determined following:
* Using the drivers from dvbsky.net the card is "Montage DS3103/TS2022" => Loading FW dvb-fe-ds3103.fw
* With the drivers from linuxtv.org the card is "Montage M88DS3103" => Loading FW dvb-demod-m88ds3103.fw

I'm a bit confused... perhaps if I use the linuxtv.org drivers, the card is recognized wrong and that's the problem?

Regards,
Chris

According to logs, everything seems to be fine. You could not compare statistics numbers between two drivers. SNR 0096 is 150DEC, which means 15dB, IIRC it was max chip could return for DVB-S.

No idea about sync etc. problems, are you sure about those? I am pretty sure it works rather well as I haven't got bug reports from PCTV 461e users which has that same demod + tuner.

Hello Antti,

the guys from [email protected] told me to contact you because of my problems with the drivers for my DVBSKY S952.

I attached the whole conversation. Currently the main problem is if i use the current drivers via git(http://git.linuxtv.org/cgit.cgi/media_build.git/about/) my single TT-Budget card works fine. But the signal from the DVDBSky S952 is very
worse: Sync problems, bad SNR, drops on video and audio... If I use the driver dvbsky.net provides (media_build-bst-14-141106), the signal on booth tuners is fine - but then my TT-Budget doesn't works anymore (see end of this mail aka starting the conversation with [email protected]).

Do you have any ideas, how I could fix this problem? Before I updated

Hello,

with the drivers from linuxtv.org and the firmware provided by your site, both cards work.

But the DVBSky card (Montage M88DS3103) do now have a really bad SNR!TT-Budget C-1501 works as expected. See the output of femon - the signal of the DVBSky card was excellent with the drivers from you site... Any idea, what could cause the problem? TV signal provided by the DVBSky sometimes drops :-(

Could you provide me any help for a solution getting the SAA7146 (TT-Budget C-1501) card working again with the kernel 3.16.0-4? With the kernel 3.2.0-4-amd64 (with Debian wheezy) and the drivers media_build-bst-13-140526 I didn't had the problems... everything worked fine. Downgrading is no solution :-)

Hello Chris,

Do all of your transponders have such issue or only some special transponders?
Could you list the parameters for them? for example, dvb-s or dvb-s2

frequency, symbol rate.

The dvbsky.net firmware "dvb-fe-ds3103.fw" is version 3.7. Annti uses the firmware "dvb-demod-m88ds3103.fw", which is version 3.B. But we test both firmwares work well. You can change one to the other's file name for check.

Best Regards,
Max

Hello,

I yust checked the SNR Level the DVBSky-Card providing with the drivers from dvbsky.net (media_build-bst-14-141106):

# ./femon -a 0
using '/dev/dvb/adapter0/frontend0'
FE: Montage DS3103/TS2022 (SAT)
status 1f | signal 7323 | snr b064 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

# ./femon -a 1
using '/dev/dvb/adapter1/frontend0'
FE: Montage DS3103/TS2022 (SAT)
status 1f | signal 7a71 | snr 2a17 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

Looks "better" than with driver from linuxtv.org via git. And I don't have any sync problems or video / audio drops.

I currently determined following:
* Using the drivers from dvbsky.net the card is "Montage DS3103/TS2022" => Loading FW dvb-fe-ds3103.fw
* With the drivers from linuxtv.org the card is "Montage M88DS3103" => Loading FW dvb-demod-m88ds3103.fw

I'm a bit confused... perhaps if I use the linuxtv.org drivers, the card is recognized wrong and that's the problem?

Regards,
Chris

Hello,

with the drivers from linuxtv.org and the firmware provided by your site, both cards work.

But the DVBSky card (Montage M88DS3103) do now have a really bad SNR!TT-Budget C-1501 works as expected. See the output of femon - the signal of the DVBSky card was excellent with the drivers from you site... Any idea, what could cause the problem? TV signal provided by the DVBSky sometimes drops :-(
