There is something rather fishy with the implementation of the thermal trip points. There are some iasl errors/warnings which point to thermal/temp: DSDT.dsl 5685: Store (GAHC (Arg0, Arg1), Local4) Warning 1093 - ^ Called method may not always return a value DSDT.dsl 5723: Method (GAHC, 2, NotSerialized) Warning 1088 - ^ Not all control paths return a value (GAHC) DSDT.dsl 5798: Store (GAHS (0x00), Local6) Error 4061 - Called method returns no value ^ The code there does not make much sense to me: - Passive cooling device only CPU0 - Quite some storing of the same things: GAHC(): Store (0x01, DTAP) Stall (0x7F) Store (0x6C, DTAP) Stall (0x7F) Store (DTAP, Local5) Stall (0x7F) Store (DTAP, Local6) Stall (0x7F) Store (DTAP, Local7) -> Ok, there is IO behind, still this cannot make much sense... The temperature should also be 20C fixed, because of Method (GAHS, 1, NotSerialized) { } _TMP(): Store (GAHS (0x00), Local6) And (Local6, 0x01, Local6) If (LEqual (Local6, 0x01)) {..} etc., etc.... The thermal ACPI stuff is really totally messed up on this system, best is to use thermal.psv=-1 (afaik) to disable passive cooling. -> Closing resolved documented, not much that can be done from OS side. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
