After upgrade my laptop, I discovered a low performance on it.
The laptop is a 2,73GHz Intel centrino and from some kernels versions to now, it had a good performance, the cpu scaling worked fine.
Now, I discover that forcing in /etc/sysconfig/cpuspeed the governors and/or max/min speeds, it don't want to run more quickly.
The laptop boots fine with the correct speed (usual speed), but when the init scripts run the service cpuspeed, the performance goes low: Only wants 800MHz!!
Yes, I played with the documentation and the values on it, but the problem began before I touch them. I discovered the problem after upgrade the kernel (some weeks ago).
Its very curious that if I power off/on or reboot the laptop, the next boot is with low speed, but if I power off, wait for 10 minutes, and power on again, the laptop boots at normal speed but when cpuspeed service goes up, the speed goes to low.
I can't change the speed using gnome or manually writing to /sys/devices/cpu/cpu0/ system files.
Has anybody got any problem as this? How to solve or work around (running an old kernel is an option)? Has any relationship with gnome cpuspeed monitor or any gnome component?
Thanks
