Sin más comentarios o advertencia, Fedora realizó el día de ayer el reemplazo de cpufrequtils actualizando a cpupowerutils. Aunque éste último es una versión muy mejorada para la gestión de energía y frecuencia de los microprocesadores, el reemplazo dista de ser transparente.

Quien utilice en su portátil o ultra-portátil un guión personalizado para controlar los gobernadores a utilizar en el sistema, necesitarás hacer algunos cambios. Si utilizas /etc/acpi/actions/ac_adapter.sh, seguramente al final de éste encuentras lo siguiente:

if [ ${ACAD_state} -eq ${online} ]
    then cpufreq-set --related --governor ${online_governor} \
        --max `get_max_freq ${online_throttle}`
    else cpufreq-set --related --governor ${battery_governor} \
        --max `get_max_freq ${battery_throttle}`
fi # Return the exit code from cpufreq-set.

Hay que reemplazar las dos incidencias de «cpufreq-set» por «cpupower frequency-set.»

if [ ${ACAD_state} -eq ${online} ]
    then cpupower frequency-set --related --governor ${online_governor} \
        --max `get_max_freq ${online_throttle}`
    else cpupower frequency-set --related --governor ${battery_governor} \
        --max `get_max_freq ${battery_throttle}`
fi # Return the exit code from cpufreq-set.

De modo tal, el guión completo queda de la siguiente manera:

#!/bin/bash
# This script should be run at boot from rc.local in case the machine booted
# on batteries, or the online governor isn't set in /etc/rc.d/init.d/cpuspeed.
# Loading the governors at boot also makes them show up in the desktop
# CPU frequency scaling monitor applet.  It should also be run from a script
# in /etc/pm/sleep.d in case the power state changed while acpid was stopped.

# Change the following two lines to use different governors.
# See /lib/modules/2.6.*/kernel/drivers/cpufreq/* for available governors.
online_governor=performance
battery_governor=conservative
# Change the following two lines to change the maximum cpu frequency reduction.
online_throttle=0
battery_throttle=1
# This list is from /etc/rc.d/init.d/cpuspeed.  If your driver isn't listed,
# but does support frequency scaling governors, add it to this list.
