Hello,

I tested the new 4.20.4 kernel and I've got a lot of ACPI errors during boot. I launched the dmesg command, and here are the results:

What does it means ?

Thanks.

I want to tell you that I haven't got these messages with official Ubuntu kernel (for example: 4.18.0-13). Very strange !!!

Comment 3 Hans de Goede 2019-02-11 13:33:33 UTC 
As discusses per email, these errors are caused by the kernel you are using not having the necessary drivers enabled.

Since you have confirmed that these errors go away when using a properly configured kernel, I'm closing this bug now.
