Well, how did you configure cpufreqd?
You need to use real kHz values instead of percentages in the
cpufreqd.conf.
Example:
[General]
pidfile=/var/run/cpufreqd.pid
poll_interval=2
pm_type=acpi
verbosity=4
[Profile]
name=hi_boost
minfreq=1267000
maxfreq=1600000
policy=performance
[Profile]
name=save_power
minfreq=0
maxfreq=933000
policy=powersave
[Rule]
name=conservative
ac=off
profile=save_power
[Rule]
name=performant
ac=on
profile=hi_boost
HTH,
