NSA325 Linux 6.17.7 eth0 not coming up after poweroff (no replies)

Hello.

Thanks Bodhi and others for your continued efforts to keep older devices alive and useful and my best wishes for 2026.

I don't know whether this issue started after upgrade to the 6.17.7 kernel. When I boot up my NSA325 (with U-Boot 2023.04-tld-1) after a shutdown/poweroff, eth0 does not come online by itself. After a hot reset the issue is not there.

See attached file for the entire boot log. Observation in the boot sequence is that Job networking.service is taking more than a minute; please ignore the 15 seconds; it truly takes more than a minute:

Only after doing a manual

ifdown eth0 && ifup eth0

or

systemctl restart networking

it acquires an ip-address via dhcp.

For now I have put

systemctl restart networking

in my rc.local as an effective intermediate solution.

Might the cause of this issue have something to do with the link-down fix (at 4.92 seconds, hardware or driver related)

ifupdown-pre.serv… synchronize boot up for ifupdown

at 40.53 seconds or is it systemd-related (e.g wrong commands, dependencies or sequences)?
