Comment 7 for bug 1777674

I am observing that in the absence of any network (interfaces not configured for dhcp/static) I can see the graceful reboot halting almost every reboot.

* Issue is observed with Ubuntu 18.04 kernel 4.15.0-23-generic
* Also observed with 4.18-rc1 hosted at http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18-rc1

Attaching the log which contains failure for both these cases.

Do you think systemd could be the suspect?
