Hi,
I just subscribed to the mailing list to submit information on the bug which
is driving me crazy since one month ago.
I have a VDR based PVR at home, installed over an Ubuntu 14.04 LTS.
Everything was working perfectly, until beginning of December. It seems to
me that something changed that broke my PVR pretty bad.
The problem is the following: tuning (zap) both tuners (it's not needed that
both are tuned simultaneously, only one after the other, in no particular
order) makes the tuners to enter an state where they can't lock the signal
anymore.
Facts:
- My TV card is a Cinergy T PCIe Dual from Terratec
(http://www.linuxtv.org/wiki/index.php/TerraTec_Cinergy_T_PCIe_dual).
- The problem arose in the form of "frontend x/0 timed out while tuning to
channel ..." in /var/log/syslog. It happened when both tuners are active,
during EPG scan. The problem does not happen if VDR is run with -D parameter
to limit the number of frontends enabled. Disabling the EPG scan with both
frontends enabled minimizes the problem, but doesn't solve it because tuning
both frontends without any EPG scan makes the error happen again.
- I initially thought about a problem in the DVB-T signal, because it all
started the 1st of December, during the transition to a new set of
frequencies in Spain.
- Everything was working perfectly before the 1st, and the problems started
suddenly.
- I setup testing board for debugging, different board and processor, less
memory, lots of Linux distros tested, Windows tested as well.
- Both tuners works in windows without problems. Confirmed.
- I have completely discarded problems/errors in hardware (because in
Windows I can enable both tuners without problems) and VDR (because I can
reproduce the problems at OS level, without even having VDR installed).
- I have almost narrowed the problem at the cx23885 driver, because when it
happens, I can restart the TV card to working conditions by executing "rmmod
cx23885" and "modprobe cx23885"; however, as with "rmmod" several
dependencies are unloaded as well, I am stuck and I am unable to go on with
debugging to find out where the problem really is.
- Tools used to test and confirm the problem are: VDR, MythTV, TVHeadend,
dvbscan, dvbv5-scan, dvbv5-zap and others
- Linux distros tested: Ubuntu, Fedora, Suse, yaVDR (not sure if the card
worked at all), MythBuntu ("dvb-fe-tool -a 1 -c DVBT" was required to force
DVB-T mode for the second tuner), and probably others
- I have a Sony PlayTV also with dual tuners, which works without any
problem. http://www.linuxtv.org/wiki/index.php/Sony_PlayTV_dual_tuner_DVB-T
So, that's why I ask for your help. How can I further debug the problem? Is
there something I can do?
BR, and happy new year!

Hi again,
I'm sorry if I sound quite rude, but I'm not sure if I am doing it right or
not. I subscribed to this mailing list in order to ask for help, or to help
with a bug that I've found (as instructed in the wiki
http://linuxtv.org/wiki/index.php/Bug_Report), but it seems to me that the
mailing list is filled up with developing messages. I don't want to
participate in the development, I am a developer but I don't have the skills
nor the knowledge.
If this is not the right place to direct my questions, I would appreciate
some advice.
Thank you very much, and best regards.

* RE: [BUG] Dual tuner TV card, works using one tuner only, doesn't work if both tuners are used

Hi dCrypt,
I'm not a developer at all. I'm not even sure why I read this list,
but can you determine if the problem is associated with a
particular kernel version? i.e. if it works on x.y.z but
fails on x.y.(z+1) you have a starting point. If you use
the word "regression" and a kernel version number you might
get more attention - but I'm only guessing.
Good luck,
blind Pete

Hi, blind Pete.
Thank you for taking your time to answer.
Yes, I tried different kernels focusing con Ubuntu distro. I don't remember the exact kernel version, but at least those included by default in the Ubuntu 12.04 lts and 14.04 lts ISO image, which worked for me. The latest Ubuntu version I tested was the nightly 15.04 from the 7th of January.
