[SOLVED] Cpufreq not loading after reboot

I followed wiki on this ,but after reboot cpufreq is not loading from /etc/rc.conf as module
This is message on boot

:: Setting cpufreq governing rules , cpu 0 1wrong, unknown or unhandled CPU?
Error setting new values. Common errors:eq/scaling_available_governors: No such - Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?

But if I do a modprobe acpi-cpufreq got this

[root@laptop ~]# modprobe acpi-cpufreq
[root@laptop ~]# /etc/rc.d/cpufreq start
:: Setting cpufreq governing rules , cpu 0 1                             [DONE]

This is a /etc/rc.conf/cpufreq

#configuration for cpufreq control

# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace
governor="ondemand"

# limit frequency range (optional)
# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="800MHz"
max_freq="2.01GHz"

# use freq to set up the exact cpu frequency using it with userspace governor
#freq=

Similar happens when I want to load governors as modules.
Laptop is acer with C2D T5800 and min and max values are  from cpufreq-info.
Can this be solved?
Thanks in advance!

Re: [SOLVED] Cpufreq not loading after reboot

Here it is without modprobe acpi-cpufreq

[root@laptop ~]# cpufreq-info
cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.

  no or unknown cpufreq driver is active on this CPU
  maximum transition latency: 0.00 ms.
analyzing CPU 1:

And with modprobe acpi-cpufreq

[root@laptop ~]# modprobe acpi-cpufreq
[root@laptop ~]# cpufreq-info

Re: [SOLVED] Cpufreq not loading after reboot

is acpi-cpufreq in your MODULES list in /etc/rc.conf?

do you see anything in dmesg and other logs?

Yes, when I put it in daemons , got something like

/etc/rc.d/functions/ :line 192 /etc/rc.d/acpi-cpufreq :no such file or directory

and repeats for governors if they are in "daemons"
I dont know how to look for logs...And what to look for in them...

Re: [SOLVED] Cpufreq not loading after reboot

Maybe I am misunderstanding you, but acpi-cpufreq should be in MODULES, while cpufreq is in DAEMONS.

MODULES=(... acpi-cpufreq ...)
DAEMONS=(... cpufreq ...)

Re: [SOLVED] Cpufreq not loading after reboot

Yes,that was mistake : acpi-cpufreq was not in modules.
Thank you verry much for help!
