For what I know, but maybe @teddyastie could confirm:
- Nothing. Typical of consumer grade hardware with buggy BIOS.
- Not I'm aware of
- No because it's a classical thing for consumer grade hardware. If you want zero message go for Dell servers. Even HPE server got sometimes buggy ACPI or stuff like that, but it's often patched during the life of the product. Consumer grade manufacturer simply don't care.
- Get server grade hardware or convince Asus to get their shit done correctly. Good luck on the latter (sadly).
