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:
