It looks like the 2.6.18 kernels are going add a new /sys/devices/system/cpu/sched_mc_power_savings entry when configured with CONFIG_SCHED_MC. This causes the cpufrequtils rc script to output a big ugly message about "invalid or unknown argument" and the standard "cpufreq-set -h" output. The /etc/init.d/cpufrequtils line: for cpu in /sys/devices/system/cpu/*; do should probably be: for cpu in /sys/devices/system/cpu/cpu[0-9]*; do
Fixed in CVS. Thanks a lot!
