Hello
I have very big problem with my processor, bacause my processor can work only on 800MHz but it should max 3GHz

I tried change this option using cpufreq but it doesn't work.

Code:
Przemek-PC przemek # cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.0 us.
  hardware limits: 800 MHz - 801 MHz
  available frequency steps: 801 MHz, 800 MHz
  available cpufreq governors: ondemand, userspace, performance
  current policy: frequency should be within 800 MHz and 801 MHz.
                  The governor "userspace" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).
analyzing CPU 1:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 1
  CPUs which need to have their frequency coordinated by software: 1
  maximum transition latency: 10.0 us.
  hardware limits: 800 MHz - 801 MHz
  available frequency steps: 801 MHz, 800 MHz
  available cpufreq governors: ondemand, userspace, performance
  current policy: frequency should be within 800 MHz and 801 MHz.
                  The governor "userspace" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).
analyzing CPU 2:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 2
  CPUs which need to have their frequency coordinated by software: 2
  maximum transition latency: 10.0 us.
  hardware limits: 800 MHz - 801 MHz
  available frequency steps: 801 MHz, 800 MHz

                  The governor "userspace" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).
analyzing CPU 3:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 3
  CPUs which need to have their frequency coordinated by software: 3
  maximum transition latency: 10.0 us.
  hardware limits: 800 MHz - 801 MHz
  available frequency steps: 801 MHz, 800 MHz
  available cpufreq governors: ondemand, userspace, performance
  current policy: frequency should be within 800 MHz and 801 MHz.
                  The governor "userspace" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).

How to fiz it?
Help :D
Thanks

It looks to me like your kernel is trying to use user land software to control the kernel speed.
I use to do that, but found that it was a bit more fuss than I wished to put up with.

I now configure the kernel as

Power management and ACPI options --->CPU Frequency scaling --->Default CPUFreq governor (ondemand)

Perhaps this would work for you and meet your needs.

PS Make sure that the right drivers in
----> x86 CPU frequency scaling drivers --->
are enabled.
Hope this works. Let me know how it turns out.

The driver was disable and now it works fine :)
Now I can use full power of my CPU :D
Thanks you very much! :D
