Public bug reported:
After switching to systemd, network-manager often fails to start
properly. Instead of startup up as it should, it seems to get into a
tight loop, burning through about 25% of each thread of my CPU. This
only happens on one of my systems, the one that is equipped with an SSD.
I have another system with the same software configuration that is
equipped with an HDD that has never experienced this problem. If I let
it sit for a long time, sometimes it eventually stops. During the time
the CPU usage is high, the following text is spammed repeatedly to
/var/log/syslog:
