Tvheadend

I am using a Pi4 with Openmediavault as a NAS and my goal is to have tvheadend running (currently in a docker container) to do dvr stuff. I use 2 Terratec Cinergy HTC Stick to get the DVB-C content - the device should have support. I used them with my old Synology NAS too.

But as soon as I start my tvheadend container I receive multiple kernel issues:

It is really spamming the syslog and I guess due to the load of information and errors all of the USB devices get disconnected (which is causing mount issues with OMV).

In tvheadend I receive a poll timeout for one of the devices every 10sec, but the other device has continuity errors.

I thought this error is caused by driver errors. I did a linuxtv media build kernel upgrade to solve it but without success. Probably this board isn't the right place because it doesn't look like a tvheadend error, but I hope this is the right spot to find someone who has an idea how I can make this work or at least give me a hint where I can find help.

Docker isn't causing this problem, I get the same error messages without using a container.
