			Disable installation of static SSDTs at early boot time

			By default, SSDTs contained in the RSDT/XSDT will be

			installed automatically and they will appear under

			This option turns off this feature.

			Note that specifying this option does not affect

			dynamic table installation which will install SSDT

			tables to /sys/firmware/acpi/tables/dynamic.



	acpica_no_return_repair [HW, ACPI]

			Disable AML predefined validation mechanism
