TIA Hi, sorry if I follow your post but I have a problem with ACPI and I think that the culprit is always Phoenix Bios as in your case (I have an HP dv2500 laptop with bios F.21)... I've read that Phoenix Bios has been planned to allow only Microsoft systems (in particular Vista) to read ACPI data and therefore manage CPU. Someone can confirm this? I can't manage cpu frequency scaling which, by the way, is supported by my cpu (C2D T7500) and in fact inside Vista works pretty well. This is the ACPI error I get when I modprobe acpi-cpufreq: [ 1008.017253] ACPI Error (psargs-0355): [\_PR_.CPU0._PSS] Namespace lookup failure, AE_NOT_FOUND [ 1008.017259] ACPI Error (psparse-0551): Method parse/execution failed [\_PR_.CPU1._PSS] (Node ffff81007cf59de0), AE_NOT_FOUND [ 1008.017293] ACPI Exception (processor_perflib-0234): AE_NOT_FOUND, Evaluating _PSS [20070126] I hope someone can clarify on this.
