Intel I226 I see. I like those I226es. Then there is possibly the option to use the igc driver instead of the generic driver. You can always test that.
Let's continue with the ec_generic.
The output shows that it is back to the ec_generic module not loading.
Can you show the output of these three commands? It should manually load the ec_generic module.

And now it works? What does "sudo dmesg" say?

Sorry Hakan, I hadn't looked at all, because I was busy searching for and reporting errors
many many thanks! I really appreciate your efforts. so just thank you again
What was the cause and do I need to do anything else now?

Wow! It works.I was ready to give up.
I don't know why it didn't work for you, exactly. More than there was a problem to load the ec_generic module using the ethercatctl script.
It will probably not work next time again.
I don't know of a permanent fix, but the two commands "sudo rmmod ec_generic" followed by "sudo modprobe ec_generic" will probably load the ec_generic module.
I don't know why it didn't work right away. But there is a fix.

I just tested it. When I restart the system, the link is down. with
lsmod | grep ec_generic
sudo modprobe ec_generic
lsmod | grep ec_generic
it works again
This is enough of a workaround for me. I can also do updates in the future with a clear conscience?

From the dmesg log and tainting the kernel, I think you have secure boot is enabled. Try disabling that in your BIOS.
Failing that I did cover very briefly how to enroll the dkms module into the kernel when you open a spoiler in my how to.
Installing a kernel module (DKMS in this case) under secure boot is denied unless specifically set as being safe. eg it taints the kernel

That could be the case, good to get an explanation to this.
Was thinking of the lack of error messages when ethercatctl tried to modprobe ec_generic,
but the error messages might be in /var/log/daemon.log and not in syslog (dmesg).
Also strange that the module can be loaded by hand using modprobe.
If that's caused by secure boot, then that's clear.
Roger can you please check for secure boot in BIOS.
And yes, no problem to update.
Hopefully it goes away with the secure boot flag.

Hi everyone, I've already done that. I've reinstalled the PC three times and always encountered the same problems. I included Mok Management during the second installation. I've done that again this time.
and yet something seems to have gone wrong:
With the workaround everything works so far (I hope) and thanks again

That dkms error is an error in the debian distribution, they included a raspberry package. Just delete it.Well I thought the secure boot would be an explanation but now I don't know.
Happy you can use it, anyway.
sudo apt remove raspi-firmwareHappy you can use it, anyway.
