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.

lsmod | grep ec_generic
sudo modprobe ec_generic
lsmod | grep ec_generic

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

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?
