 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,
