I had explictly defined "eth0" in /etc/default/idplugd and I went through all 3 possible combinations. I have not tried "dpkg-reconfigure ifplugd". The testmachine only has eth0, no wifi.

I have removed that as you suggested.

But I have news on the "openssh hangs on boot"-issue: kernel 4.9 (from ascii) works as expected. But kernel 4.19 from beowulf lets openssh hang on boot. Same computer, same config, just kernel changed. But this is different:

Feb 16 22:24:23 localhost kernel: [    6.033782] Bluetooth: BNEP socket layer initialized
Feb 16 22:24:24 localhost kernel: [    6.978681] random: crng init done

Feb 16 22:09:14 localhost kernel: [    5.062847] Bluetooth: BNEP socket layer initialized
Feb 16 22:09:44 localhost kernel: [   34.345896] random: crng init done

So openssh is blocked by random, which by some unknown reason takes ~ 30 seconds to start on 4.19 (in contrast to ~ 1 second o 4.9)

Any suggestions on how to proceed?
