it is pretty much 100% reproducible for me. root 1724 0.0 0.0 15780 6480 ? Ss 05:06 0:00 systemd-tty-ask-password-agent --watch --console root 1733 0.0 0.0 18732 6684 ? Ss 05:06 0:00 \_ systemd-tty-ask-password-agent --watch --console=/dev/tty1 but from the log it looks like the left over systemd-tty-ask-password are from the system trying to unlock the additional disk after the initrd is done.
