Hello all,

I got an Fujitsu-Siemens Amilo A 1667G notebook, with an AMD Athlon 64 3400+ Mobile processor and got a minor problem with it.
I compiled my own kernel and set the CPU govenor to Userspace and I compiled the ondemand and conservative options built-in.
Next I emerged cpufreqd, the thing is that going to 2.20GHz works fine, but the processor doesn't revert back to a lower speed. (It doesn't matter if I use cpufreqd or not, it just refuses to go any lower then 2.20GHz. The tool I am using to switch between CPU speeds is the gnome-cpu frequency applet.

Are you using the ondemand governor or the conservative? I had the same problem when I used conservative. Try setting the ondemand and see what happens.
