Accordingly my laptop's cpufreq doesn't run anymore. Until kernel 3.13.8, acpi-cpufreq has been loaded automatically as expected. If I try to load acpi-cpufreq manually on 3.14, # modprobe acpi-cpufreq modprobe: ERROR: could not insert 'acpi_cpufreq': No such device Strangely if p4_clockmod was loaded initially, acpi-cpufreq can be loaded sucessfully too. My laptop's cpu is PentiumM though. # modprobe p4-clockmod # modprobe acpi-cpufreq In this case, available frequencies are messed up. # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 212500 425000 637500 85

Have you installed the YaST power utility? Open YaST / Software / Software Management, search on power and install yast2-power-management. Then, a new system item will be added. You must restart YaST to see it. Also, go into System Services (Runlevel), enable pm-profiler, start it and accept the new setup. Then, you can run YaST / System / Power Managem and select Low Latency Computing which should run your CPU at full speed.
