Hi jbitor
I think you have a slightly different problem. The dmesg output shows at the end that some firmware could not be loaded while I had the problem that the driver would crash and no adapter was visible in tvheadend. maybe the firmware files for your card are missing on your system

Hi,
I haven't checked the kernel change logs, but current nightly for generic should come with kernel 5.10.47. So maybe it is worth a try.

Hi mglae ,
since my clean install of beta4 my system is running fine dvb-wise.
I'm just trying to help @mpavlis76 to figure out his problems with the combination of a tbs and a technotrend dvb card and hoping to learn a bit doing so. But I think it could be worth a try for him to test the "recent kernel" driver package.
thanks
MadMax
Hi mglae ,
thank you for your reply. Just for clarification, depmod is run, when an additional driver package ist installed/used?
I ask because I just checked the output from dmesg on my system (now beta5) and the part with the kernel-overlays-setup ends with "kernel-overlays-setup: done" and no nvidia.ko error.
I only use the base package because I only have the TechnoTrend cards installed.
Thank you again for your support
Best regards
MadMax
Hi,
I feel with you. This is a very unsatisfying situation. Can you try to use only the standard dvb drivers? This would result in the tbs card definetly not working but maybe the technotrend card could be recognized.
If I see it correctly something messes up the "kernel-overlay-setup" which also results in the nvidia.ko kernel module not being found.

[ 1.373206] depmod: ERROR: fstatat(5, nvidia.ko): No such file or directoryFor me this is the first indicator that something is going wrong.
As I stated before, I only have 3 TechnoTrend cards installed but something during the upgrade from beta1 to beta2 activated the crazycat and digital devices driver packs and even setting back the dvb drivers to standard with the driver selection addon didn't help.
I think maybe a developer ( mglae or HiassofT ?) or someone with more knowledge of the inner workings of the LibreELEC boot process could have a closer look.
Or maybe with the current kernel-overlays-setup system it is not possible to have different dvb cards installed that need drivers from the base system for one card and from eg the crazycat addon for the other.
Keep trying

Hi,
it looks to me like it is again the saa7146 driver for the Technodtrend card is crashing. If I remember correctly the driver selection addon was not present in beta1 but I could be wrong because I don't need the TBS or DigitalDevices drivers.
Have you tried the suggestion from mglae?
- For an easy clean installation test create the installation stick, boot it and type run at the Syslinux boot prompt. The system will only run from the USB stick and not modifying your installation.
This way nothing on your disk will influence the libreelec system. If the saa7146 driver loads successfully you should find a file called frontend0 in the /dev/dvb/adapter0 directory (that is if the TechnoTrend driver loads first, if the TBS driver loads first it could be adapter4).
On my system something during the update from beta1 to beta2 messed things up so the saa7146 driver would crash. As I wanted to replace my system drive anyway I chose to wipe the new disk and did a fresh install of beta4 and the saa7146 did not crash.
Good luck
MadMax
sorry for hijacking your thread. As my problems where also with TechnoTrend cards I thought we might have the same issue.
Did you do a clean install of beta4 on your 2nd disk?
In your place I would try libreelec 10 beta1 (9.95.1) and check if your dvb-s cards are recognized with that version.
Good luck
MadMax
A clean install of beta 4 did the trick.
I guess something goes wrong when updating from beta1 to a newer beta or recent nightlies and the driver module for saa7146 crashes at startup and prevents a clean reboot.
thanx to all and keep up the good work
MadMax
I was suspecting that it is the same driver. But I was not aware that the crazycat and Digital Devices drivers were enabled.
I checked and the driver addons were all disabled and I also used the modules selection to set the dvb drivers to the libreelec standard modules.
I will try a clean install of beta 4 and/or newest nightly on a new disk.
Hi,
I have a similar problem with my 3 Technotrend PCI DVB-C cards.
With Libreelec 10 Beta1 everything is working fine but since Beta2 the frontends are not initilized.
In beta1 I can find 3 adapters in /dev/dvb/ (adapter0,adapter1,adapter2) each with demux0 dvr0 frontend0 and net0.
Since beta2 there is only 1 adapter and only demux0 dvr0 net0, frontend0 is missing. Also since beta2 the system hangs at reboot because /flash cannot be unmounted.
I checked with the latest nightly.
You can find the output from dmesg here:
10 beta1 9.95.1
10 nightly 20210617
Thank you all for your hard work with Kodi and Libreelec
MadMax
