# modprobe p4-clockmod.ko FATAL: Module p4_clockmod.ko not found

odd that you modprobe'd p4-clockmod but it complained that p4_clockmod is missing...

or is this a typo in your post?

oh...typo (copy wrong messgae). I already tested the p4-clockmod.ko just now. both is outputted same message: (do again)

------------- dump of screen ------------

# modprobe acpi-cpufreq.ko FATAL: Module acpi-cpufreq.ko not found

# modprobe p4-clockmod.ko FATAL: Module p4_clockmod.ko not found

--------------------------------------------------

I first tried the acpi-cpufreq.ko because the module is recommended by kernel 2.6.20+. After not effect, I also tried the p4-clockmod.ko since my machine is intel processor:

And, I grep the "est" in /proc/cpuinfo, and it is there. so, the cpu hardware should have opened the support.

And help?

No i do not think it is a typo because I get the same exact error that it is missing where as it was available 2 kernels ago?

Do you mean modprobe can not find the proper module file when it faces two and more kernels in same machine? I think this would not happen.

File Bug Report?>

where can I find the fire bug report?

Best,

Ian

You have to write:

# modprobe p4-clockmod

It means no "ko" extension.

Same result.

The p4-clockmod is not in /lib/modules/2.6.29.3/kernel/arch/x86/kernel/cpu/cpufreq/.

But I tried the acpi-cpufreq.ko and got the same result.

Any help?

Thanks,

That error tells me most likely your hardware is not compatible with the driver, check 'dmesg' for any messages the driver might of generated when it was loading.

there are nothing output by "dmesg" when I tried the

# modprobe acpi-cpufreq

and

# modprobe acpi-cpufreq

The output message is same whenever how many time you execute above two commands.

What CPU are you using? I get the same message on this system I am on, a really old dual xeon single core system. p4-clockmod loads though if I recall right even though you can adjust the clock speed the power usage won't be impacted because the voltage won't change, at least on this class of processor.

My machine is DELL 360 with dual cores. The CPU info can be seen from /etc/cpuinfo:

If you want more information, please tell me how to do next.

Thanks,

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?

Thanks agin,

Ian
