As for the *original* bugreport, this dmesg output: Jun 26 20:55:57 lappy kernel: [ 494.227246] powernow-k8: BIOS error - no PSB or ACPI _PSS objects
Tells me that your BIOS is broken. This cannot be fixed by the Linux kernel. Please verify whether there is a more recent BIOS for your system, perhaps your manufacturer has already released a fix. If not, you could request them to do that. Also, perhaps there's a custom ACPI "DSDT" for your system available for Linux that provides a PSB or _PSS table. There are some HOWTO's available that will help you do that. It could also be that a BIOS option is blocking the PSB or _PSS objects, something in the line of "intelligent power managment" or so. My Asrock motherboard has such an option, I don't remember what it is called. (I'm not immediately switching the status of this bugreport to "Invalid" as I will wait for your feedback first) As for all the noise in this bugreport, please fill in your own bug reports... -- Hardy x64 on AMD Turion not CPU scaling properly https://bugs.launchpad.net/bugs/231534 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
