Comment # 14 on bug 1184817 from 
Happened again, this time more similar to 1184836 (which I now think is
actually the same bug):
disconnected from wired ethernet for no reason, then unable to reconnect, then
could not connect to WiFi either. At that point I shutted down.


I had a terminal open with "journalctl - f" running. The last lines of output
were these:
