It looks like there is an oops when udevadm trigger writes "add" to some module uevent. Can you edit /lib/systemd/system/systemd-udev- trigger.service and add --verbose after subsystems?
The line would be like this: ExecStart=/bin/udevadm trigger --type=subsystems --verbose --action=add ; /bin/udevadm trigger --type=devices --action=add Then, reboot, and get journal logs from systemd-udev-trigger. I guess journalctl --unit=systemd-udev-trigger might show it. Thanks.
