So if it is a bug, it is probably an upstream bug. Agreed - I was asking whether you regard this as a real upstream bug, or a broken ACPI implementation not worth fixing. > It would be good to verify that ACPI events in general > are working on the box -- eg. the power button etc -- as a failure > there would also be more interesting than unchanging temperature. The power button does generate events, so it's not completely broken. I guess this can just be passed off as a small BIOS bug? If you'd like us to open a bug for it anyway, just say. Thanks! Daniel
