Package: cpufrequtils
Version: 008-1
Followup-For: Bug #666499

I'm also seeing this on a Dell Studio XPS 8100

The first CPU gets the correct frequency settings on resume, but the
others don't.

On boot - set via /etc/default/cpufrequtils:

ENABLE="true"
GOVERNOR="ondemand"
MAX_SPEED=2133000
MIN_SPEED=0



# cpufreq-info | grep 'be within'
current policy: frequency should be within 1.20 GHz and 2.13 GHz.
current policy: frequency should be within 1.20 GHz and 2.13 GHz.

current policy: frequency should be within 1.20 GHz and 2.13 GHz.
current policy: frequency should be within 1.20 GHz and 2.13 GHz.


After a suspend-to-ram, then resume:

# cpufreq-info | grep 'be within'
current policy: frequency should be within 1.20 GHz and 2.13 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
current policy: frequency should be within 1.20 GHz and 2.80 GHz.


i.e. first CPU retains settings, others revert to boot-time defaults.


I don't know what code (kernel/userspace/BIOS) should be responsible for
restoring the CPU frequency settings after resume, but it's not working
on this system the Jessie kernel.

As a workaround I created this script as 
/lib/systemd/system-sleep/cpufrequtilsrestart

#!/bin/sh
case $1 in
        pre)
                # Do nothing
                exit 0
                ;;
        post)
                echo "Setting CPU frequency preferences following system resume"
                systemctl restart cpufrequtils.service
                ;;
esac
