Hello, i've an Xen Server running on AMD K8 CPU. With Xen-3.4.0 and 2.6.24-24-xen Ubuntu Dom0 Kernel i can use cpufreq via: cpufreq=dom0-kernel But on 2.6.31.6 pv_ops Kernel i get: powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ processors (2 cpu cores) (version 2.20.00) [Firmware Bug]: powernow-k8: No compatible ACPI _PSS objects found. [Firmware Bug]: powernow-k8: Try again with latest BIOS. I've installed latest BIOS. I've read that cpufreq=xen only work with K10. Is it so? On Intel CPU this Kernel make cpufreq fine with xen-4.0.0-rc1. Regards, Stefan Kuhne
