Hello, On Fedora 16, CPU scaling works fine for me. On Debian, I was able to determine minimal/maximal frequencies of CPU-s by looking to files like this: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_{min,max}_freq Is there a way how can I do the same on Fedora? Is there a way how can I determine that CPU scaling is turned on, on a given machine?
