I get this error as well, and I do NOT have sddm installed, so the provided "fixes" don't work. I cannot boot to a graphical user interface by waiting, I don't have "quiet" enabled and I'm using mdm.
The only way to boot is to switch to another tty (F1 - the only one available) and execute "sudo mdm restart" manually. This is a critical error, not a trivial one, as i has completely broken the boot process on my laptop.
