The following command # modprobe cpufreq_ondemand can be executed and nothing is output. However, still no "cpufreq" directory is created in /sys/devices/system/cpu/cpu0/ after the command is done. BTW, I don't know where can I check whether the hardware is supporting the CPUfreq. I just learn from maillist if someone want to check the cpufreq support in hardware he can run the following commands to do checking: # grep est /proc/cpuinfo Any helps? Thanks agin, Ian
