cpufrequtils error with Core i7 "Haswell" 4771 on Funtoo Linux

Hello, I am a member of Funtoo Linux OS.
I've written about the problems relating to bugs.funtoo.org cpufrequtils with the cpu of my system.
I read of addressing this email address .......
I hope I did not disturb you.

Actually i use kernel:

ci7ht ~ # uname -a
Linux ci7ht 3.12.13-gentoo #1 SMP PREEMPT Fri Mar 28 23:54:21 CET 2014 x86_64 Intel(R) Core(TM) i7-4771 CPU @ 3.50GHz GenuineIntel GNU/Linux

There are suggestions for this trouble ?

Thank You Very Much

Alessandro.

cpufrequtils is outdated for quite some time.
cpupower is the successor (afaik some package it as cpupowerutils).

If you still have problems, best use the original sources:
tools/power/cpupower
from the kernel sources and report problems here and add me to CC.
