I had similar problem in the past. I used 586 kernel and it didn't work. Do you have 686 kernel? If yes, can you send us the output of the following commands:
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
# modprobe cpufreq_ondemand
There does not exist the "cpufreq" directory. 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?
I found the problem location why the "cpufreq" directory is not there. I *HAVE NOT* opened the speedstep in my bios. OMG
wasting so much time~~ I am sorry~
Thanks for all,
Ian
