First of all, if I'm reading your messages correctly, you've got two drivers trying to perform CPU power management at the same time? You should probably remove or disable to frkit powernow driver. I think you might as well remove it as I believe it only supports single processor systems and you have two processors. Both drivers seemed to be having issues with the ACPI _PSS object. Usually when I see problems like this it is due to one of two things. 1 - Enhanced SpeedStep has not been enabled in the BIOS setup.
Yes, it is enabled in setup - basically on HP you have a choice between enable/disable - its enabled. 2 - The BIOS is not returning valid _PSS objects.
The first is easy to check for. The second usually requires dumping the ACPI tables with a utility like iasl and then inspecting the output to see what the _PSS definitions look like. Unfortunately, you need to know something about what they are supposed to look like in order to tell what, if anything, is wrong with them. What kind of system do you have?
HP Pavilion dv6209tx - bought this year around three months ago. It has the latest update, F.27 from HP - I'd assume that it isn't buggy or problematic given that both SLED 10 SP1 and Windows Vista sing happily on the machine. According to SLED 10 Sp1: [EMAIL PROTECTED]:~> cat /proc/acpi/info version: 20060127 [EMAIL PROTECTED]:~> I'm assuming thats the version of ACPI, I can't get a version number unfortunately. Matthew
