Do you already have latest linux-firmware package?

Can you check latest mainline (currently v6.6-rc6) instead?

Can you also attach full kernel logs from both systems?

sorry. My backup laptop broke down while trying, so I wont be able to
build and test a selfbuilt kernel any time soon.

I was able to make the device partly work on
LibreElec12@raspberry pi 3B+ kernel 6.1.58
dmesg see http://ix.io/4JKJ

But I wasn't able to tune into anything yet.
The Hardware ID is a dublette and pulled a wrong driver on LibreElec.
After blacklisting em28xx, the correct driver was loaded.

I still get the message regarding firmware not loaded because buggy.

 From what source? Ubuntu repo?

I manually fetched from openelec github:
d8da7ff67cd56cd8aa4e101aea45e052  dvb-demod-si2168-02.fw
c8e089c351e9834060e962356f8697b8  dvb-demod-si2168-b40-01.fw
d643a75d2ced161bc5fb635aec694d9f  dvb-demod-si2168-b40-01.fw.bak (bad?)
0c3f6bc5028bc37cfbf3a16d480bbaa5  dvb-usb-it9303-01.fw

Re: si2157 not working at all?

Well,

I was able to make a fresh ubuntu install and build 6.6-rc7

find the logfile here:
https://pastebin.com/9zsRuYFv

comments inside, at the end.
the last lines are:

si2168 8-0067: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
si2168 8-0067: firmware version: B 4.0.25
si2157 9-0063: device is buggy, skipping firmware download
si2157 9-0063: firmware version: \xff.\xff.255

so even in the newest kernel, the chip is marked as buggy.

could someone please have a look what is the problem with si2157?

here seems to be a patch for kernel 4.19
https://github.com/brandsimon/debian-kernel-terratec-cinergy-tc2

thank you very much

Jan

Please don't top-post; reply inline with appropriate context instead.

What patch do you mean on that repo? Can you try applying that to see
if it helps?

Confused...

Oops. Thank you very much.
I was on the wrong trace all along.
Sorry, for bothering. I have tried hard to learn a little bit of kernel
development, but I am far from all of you :o)

could someone please change the kernel message to something more specific?

for example:

drivers/media/tuners/si2157.c
153c153
<                        "device is buggy, skipping firmware download\n");
---
 >                        "firmware upload does not work, using firmware
already installed\n");

thank you very much
