Ok, but is not working fine.

The last try:

1. Power off the laptop along 2/3 hours.
2. Power on and log into gnome.
3. The cpuspeed monitor shows that all is working fine.
4. Some minutes after, the speed goes down to 800 MHz and no more wants

to grow up. I can't change to force performance or using userspace and select the speed.

Any help more about?

If I launch any heavy compilation (as kernel compilation), the speed don't want to grow up. Really is working fine under these circumstances with the performance governor selected?

First, please do not top post in this forum / on this list.

Second, try this:

dd if=/dev/zero of=/dev/null <some huge number of blocks>

and see if that drives your cpuspeed up.

BTW, how are you checking the cpuspeed? Are you looking at /proc/cpuinfo?
