Went back and rebooted it to the last 3 rt kernels, no network for -rt12.
Got normal net from -rt11, reboot back to -rt12, works, ditto -rt13
works, and the default let it time out works.
WTH. Come back to house again, ssh now works but keys are wrong, login
reboot it from here, ping is back in around 40 secs, takes an ssh login a
few seconds later. Everything seems normal. Go back up, kill the power
to the monitor and the lathe this machine controls, come back and reboot
it again. Works. WTH? I am glad, but I've also made a few trips up the
hill on 86 yo pins and wasted at least 2 hours doing it. And I did not
touch anything with an editor. And while it is working, there still is
not a /dev/enp1s0 to be found except in an "ip a" output. Or
in /e/n/interfaces. udev makes this stuff up out of whole cloth now?
Call me bumfuzzled, this does not make sense.
