Hi! I'v just installed the Kernel 2.6.9 on my iBook 2.2. I compiled in the userspace and ondemand governor. Userspace is the default. I tried to change this by echoing ondemand into /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor But the setting does not change. It stays at userspace. cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors says ondemand userspace So the ondemand governor is available, isn't it? Martin
