"powernow-K8:BIOS error - no PSB or ACPI_PSS objects" 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 if C'n Q has indeed been disabled in the BIOS, and then determine what you want. If you don't want C'n Q you can ignore this message (powernow-k8 has been built-in in the kernel so you cannot prevent this message from being displayed). -- powernow-K8:BIOS error - no PSB or ACPI_PSS objects https://bugs.launchpad.net/bugs/382220 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
