I have following issue but I do not know were I can find useful logs to understand what is going on.
My machine is a very standard Gigabyte Mainboard with integrated Ethernet. Only one NIC is present on the system. The issue started about 3 month ago, I always wanted to investigate but I am too annoyed now, so I really want to solve it.
Take a typical start up: the machine is on a dlan Ethernet were a Devolo 1200 (with a small OpenWRT like OS running on it) is managing the Ethernet interface. When I start up, the system (with wicked as network setup, there is no WLAN on the machine) boots fine. But when arriving at the Plasma desktop you have no network. If you try to restart networking services (e.g. sudo rcnetwork restart) it does but you do not have network. I also tried to restart every wicked service in yast but no network and no error log.
But if you simply reboot the machine all works as expected.
Now I tried this also without a graphical user session, it is the same, so the issue is IMO not bound to Plasma. I thought it might be that this is a timeout with the dlan being in energy saving at the first bood and awaken at the second. But wouldn't wicked wait until the interface has an address? Wouldn't it complain logging clearly in journalctl? Anybody else in the past encountered such an issue?
Thank you in advance.
I think this one is still in the information gathering stage. Others have suggested looking at a console session. I would suggest taking a look at whether the BIOS has anything to do with the problem. Perhaps power up and reboot when GRUB comes up and see whether the problem is still there? Plus take a look at the BIOS settings for the ethernet interface. Another thing to try is to place an ethernet switch between the Devolo 1200 and the PC, to see whether the BIOS is just ignoring the ethernet interface because it thinks nobody is at home in the Devolo 1200.
