"Your BIOS does not provide ACPI _PSS objects in a way that Linux understands" almost always means that Cool 'n' Quiet has been disabled in the BIOS. This kernel message also isn't really an error, it just tells that the kernel will not use CPUFREQ powernow-k8 support because Cool 'n Quiet has been disabled, so it's doing exactly what is requested.
Please verify that C 'n' Q has indeed been disabled in the BIOS, and then determine what you want. If you don't want Cool 'n' Quiet you can ignore this message (powernow-k8 has been built-in in the kernel so you cannot prevent this message from being displayed). (To enable, go into your BIOS and go to "Advanced" => "CPU Configuration" => "Cool 'n' Quiet" and set it to "Enabled") -- AMD 6000+ Cool'n'Quiet does not work (ACPI) https://bugs.launchpad.net/bugs/347002 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
