Console messages shown on power off

[Saurav Sengupta]

On powering off (shutting down) the computer (Kubuntu 21.04 as on 8 Mar 2021), console messages (probably from the kernel) briefly appear before the Plymouth splash screen does, creating a less-than-desirable user experience. After that the messages disappear and the regular splash screen appears until the computer powers off.

I don't know what is causing the problem, but it wasn't there before. I've tried all combinations in /etc/systemd/journald.conf and /etc/sysctl.d/10-console-messages.conf, but to no avail.

Sorry. As I said, I'm unable to find out which package is causing the problem. Perhaps someone can help?
