Maybe an edit to \ in /etc/sysconfig/apmd.../cpuspeed/ to correct it perhaps. Is cpufreq-utils installled? microcode-ctl? Last time I checked red hat stays current on backporting when newer microde is released thus centos does also. Some have to be ultimatly defined in apmd and cpuspeed to load them or not. John
