acpi curve. It is necessary to patch the DSDT table, but in fact it is easier to put a bolt. If there are no problems with iron, then everything is ok. As an option, kick the vendor to fix the bios, they are completely lazy, damn it #[email protected] But if everything is bad, but you need to take iasl, dump tables, patch. All info is on google. You can touch the Mac drivers, they have a special olympiad
PS As for secure boot and other things, these are no longer acpi problems, it's you who screwed up the boot somewhere and that's another story.
PPS If perfectionism haunts, then you can set loglevel=3 in the kernel parameters, then the acpi error will not be visible. As well as many others.
