journalctl error Arch do I need to take action?

I don't seem to have any issues. Everything works great, but I'm going through and learning more about journalctl and system maintenance. I want to learn as much as I can and keep things squeeky clean for the foreseeable future. Anyways, I was going through Arch system maintenance wiki and one of the suggested commands was

journalctl -p 3 -xb

this was my result:

[derek@archlinux ~]$ journalctl -p 3 -xb

Again, I don't seem to be having any issues. Everything works that I can tell. Everything is up to date as of today. Cache is clear, no orphans, etc. I probably would have kept going indefinitely without knowing a thing until I came across the Arch System Maintenance stuff. If I don't need to do anything, thanks!

This is normal kernel messages when kernel want's to do something not supported by firmware.

Thanks! I kind of figured as much since everything is fine. I just thought I'd ask.
