Each time I reboot my laptop, that's running Kubuntu 20.04, I see this message right before it reluctantly reboots:
systemd-shutdown: Failed to finalize DM devices, ignoring
Also, rebooting takes longer than it should while this message is being displayed.
I've found a bunch of people asking about this, but I haven't yet read one solid answer.
What does this message really mean, and how can I fix this "failure"? The goal is to have no unnecessary delays when I initiate a reboot.
