(The ones that get set when BIOS (in DSDT) calls e.g. osi("Windows 2006")) Something like: if (osi("Windows 2006")) Store(1, DTSE) Maybe you find out what the DTSE or MPEN variable is good for, is set by some _INI function of a specific device or whatever? Best you create a bug for that at bugzilla.kernel.org (and add me to CC or post the bug no). Full (or none) fan is a real blocker bug that should generally be resolved. Does this BIOS expose an ACPI fan device correctly? If yes is: echo 1 >/proc/acpi/fan/*/state or: echo 0 >/proc/acpi/fan/*/state echo 1 >/proc/acpi/fan/*/state echo 0 >/proc/acpi/fan/*/state or whatever also a workaround?
