Hello, https://01.org/linux-acpi/documentation/overriding-dsdt shows how to override SSDT and it says that we need to set 'acpi_no_auto_ssdt' kernel parameter. However, the kernel parameter name was changed by a94e88cdd805 ("ACPICA: Tables: Avoid SSDT installation with acpi_gbl_disable_ssdt_table_load.") Could you fix the description? Like as follows: === If you need to modify the code present in an SSDT, then combine all of the SSDTs into a DSDT override, modify it as necessary, and boot with a kernel parameter (*) to prevent Linux from automatically loading the SSDTs listed in the RSDT/XSDT. (*) Linux-3.15 and before: acpi_no_auto_ssdt Linux-3.16 and after: acpi_no_static_ssdt === Thanks, Masa
