Looks like a found a simple reproducer (this is on my work laptop) done during normal runtime of the system: $ rm /etc/udev/rules.d/70-persistent-net.rules $ while true ; do echo add > /sys/class/net/eth0/uevent ; done I let this run for one or two seconds and had over 100 entries in 70-persistent-net.rules. udevd went totally nuts and consumed almost 100% CPU, but a simple systemctl restart systemd-udevd.service fixed that. So, while I don't have a solution yet, at least I have now a simple way to reproduce it reliably. Therefor marking the bug accordingly. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
