These errors are shown every time I boot my laptop.

My laptop is running Arch Linux (kernel 4.20.1). But this happens with OS like Manjaro, Antergos, ArchLabs.

It doesn't do any harm, but if I want to load plymouth theme and add i915 to startup module, my laptop doesn't boot until I remove the line by chrooting.

It's worth noting that I do have:

Hello SGosw5, For Linux-related issues on third-party motherboards/systems, we recommend contacting your Linux vendor and use their distribution resources. It is worth noting that Intel has not validated these operating systems. Hopefully, a community peer may shed light on these errors you are receiving. Wanner G.

Ok, thanks. I might have to mount and look at Linux Mint/Ubuntu locally, because the plymouth works fine there. I do get these errors, but my system boots with the driver...

The error is on my Dell laptop. But my desktop also has Intel i3 processor (4th gen) where I installed plymouth on my own. It works fine. And also I get no error while booting my system or via journalctl...

It might be really a motherboard issue. Thank you.
