ho provato a fare come ha suggerito ercolinux:

root@openmamba ansax]# rmmod p4-clockmod

[root@openmamba ansax]# cpufreq-info

cpufrequtils 0.4: cpufreq-info (C) Dominik Brodowski 2004

Per favore, comunicare errori e malfunzionamenti a linux@brodo.de.

analisi della CPU 0:

nessun modulo o modulo cpufreq sconosciuto per questa CPU

[root@openmamba ansax]# modprobe speedstep-centrino

FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.24mamba/kernel/arch/x86/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

[root@openmamba ansax]#

qualche idea?

grazie, andrea.
