enabling "cool 'n' quiet" on linux

hi all,

i'm posting here too as i feel this issue is more related to "hardware" than my distro ;-)

i want to enable "cool 'n' quiet" on my linux box, and any pointers would be welcome ;-)

distro: mandrake 10.1 official (3-cd download version)
version: 2.6.8.1-12mdk
procesor: amd athlon64 3000+ (754pin)
motherboard: asus k8v

i've enabled "cool n quiet" and acpi 2.0 in the bios. (the "q-fan" feature works like a charm)

here are the logs:
******************

[root@blackbird proc]# modprobe powernow-k8
WARNING: Error inserting processor (/lib/modules/2.6.8.1-12mdk/kernel/drivers/acpi/processor.ko.gz): No such device
FATAL: Error inserting powernow-k8 (/lib/modules/2.6.8.1-12mdk/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko.gz): Unknown symbol in module, or unknown parameter (see dmesg)

[root@blackbird proc]# dmesg|grep powernow-k8
powernow-k8: Unknown symbol acpi_processor_unregister_performance

powernow-k8: Unknown symbol acpi_processor_register_performance
powernow-k8: Unknown symbol acpi_processor_unregister_performance
powernow-k8: Unknown symbol acpi_processor_register_performance

i read somewhere on the net that the bios on my mobo didnt implement the acpi spec properly, or something like that (i'm not sure if thats true, though). hoping to get cnq working....

kind regards,

cool n quiet? Sorry lost me. I just stuck in extra fans and ran them off of the 5V rail...same air flow but much quieter and no kernel changes.

To check your current cpu speed you can do:

Code:

cat /proc/cpuinfo | grep MHz

The grep bit is optional, neatens the result up a bit though

Good thing about c'n'c - less noise from the cpu fan and, I would guess, less electricity consumption

You might need to have a look in your kernel and see if there's anything else that needs to be enabled (or possibly think about about trying a more recent kernel, see if that helps).

I use 'speedfreq' to dynamically change cpu speed as 'powernowd' stopped working on my computer as of kernel 2.6.11
