[SOLVED] eth continuously readded, NETDEV_CHANGE generated

Hi,

I upgraded my system on 10th June after a week (thus previous upgrade was 3th June) and now I suffer with periodic network reconfiguration. I can see this in dmesg each ~16s:

This disturbs web browsing, sometimes  the response from server is lost. Even if I'm connected via wifi. It is also possible the issue in logs did not start with upgrade, but now it is observable by user when working with the system.

I also tried to revert the upgrade using arch archive to no avail. Maybe it is in some config file.

Please let me know if someone has any clue what to examine / fix.

Best regards

Pavel

Re: [SOLVED] eth continuously readded, NETDEV_CHANGE generated

For the record, is was caused by docker-compose, which remembered running containers and tried to start them after reboot. However the environment was not complete, which leads to periodic container restarting and docker network recreating.

It can be easily find by listing network devices.
