PRMT not found The help text for the Kconfig option `ACPI_PRMT` suggests it’s mainly used for server systems, so the warning does not apply to a lot of systems. Therefore, in my opinion, the option should not be selected by default, or the warning be removed or demoted, and phrased in a way, that users can understand the consequences. Kind regards, Paul
