After conversation via email (thanks andy green) that this might have
something to do with power management. Turns out that ondemand scaling
is turned on about 60 seconds after boot. From etc/init.d/ondemand:
#! /bin/sh
### BEGIN INIT INFO
# Provides: ondemand
# Required-Start: $remote_fs $all
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: Set the CPU Frequency Scaling governor to "ondemand"
### END INIT INFO
PATH=/sbin:/usr/sbin:/bin:/usr/bin
. /lib/init/vars.sh
. /lib/lsb/init-functions
case "$1" in
start)
start-stop-daemon --start --background --exec /etc/init.d/ondemand --
background
;;
background)
sleep 60 # probably enough time for desktop login
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
do
[ -f $CPUFREQ ] || continue
echo -n ondemand > $CPUFREQ
done
;;
restart|reload|force-reload)
echo "Error: argument '$1' not supported" >&2
exit 3

echo "Usage: $0 start|stop" >&2
