Package: cpufrequtils
Version: 008-1
Followup-For: Bug #622277
I do have the sampe problem. I have an E8400 with 2x 3.0Ghz running with
2.0GHz.
It's not possible to get it to 3.0Ghz.

It seems like the full power is only used when the system is booting up. It
does work with the latest OpenSuse Gnome LiveCD.
I also have tested the linux-image 3.4-trunk-686-pae with no effect at all.
