...wants to tell you that there seems to be a cyclic dependency during boot with dbus.socket and socket.target, and systemd interrupts that somehow in order to try to get along, leading in your case to an unbootable system. (In other cases, such messages are only informative if the system boots up proper, because such a cycle then could be resolved later).
If you manage to boot that system in multiuser.target (init3) or emergency.target, please give the outputs from the following five commands (*)
systemctl status dbus.target
systemctl status dbus.socket
systemctl status sockets.target
systemctl show dbus.socket
systemctl show sockets.target
To see if something hangs or is waiting for any external device or outsourced partition, please give also your /etc/fstab
(*)
Hint: the commands might show their ouput in a pager (less/more). If you want them directly on screen (or >direct them in a textfile or | to a paste service) you can use the option '--no-pager' like for example 'systemctl show sockets.target --no-pager' (two dashes - -)
