Well, i've entered the following bug in the kernel bug tracker: http://bugzilla.kernel.org/show_bug.cgi?id=12948
It was confirmed that the Asrock BIOS doesn't contained the required _PSS tables - which is an error on their part - nothing Linux can do about. The _PSS tables are needed for powernow-k8 in case of a multi- core CPU. So, i emailed Asrock about the problem. Guess what they'll tell you: "regarding Linux: have to say sorry, ASRock does not test or support the use of Linux OS. We cannot guarantee that ASRock motherboards will work with Linux without problems." So, better refrain from Asrock for future buys. I surely won't recommend them to anyone in future. -- Error on Boot: [Firmware Bug]:Powernow-k8: Your BIOS does not provide ACPI_PSS objects in a way that Linux understands. https://bugs.launchpad.net/bugs/331691 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
