The BIOS? :) Seriously, the acpi-cpufreq driver needs good data from the BIOS's ACPI tables to be able to do anything. Try booting with 'cpufreq.debug=7' added to your kernel boot params, and you should get some more data on why its failing to work, but pretty sure its the BIOS at fault. -- Jarod Wilson jwilson@xxxxxxxxxx _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
