Hi
Need some input as to whether this is a bug or expected behavior.
In order to have working cpu freq scaling i need to modprobe acpi-cpufreq manually. ie it does not get loaded during boot
I see this in both 11.3 livecd and in current factory ( using kernel 2.6.37-18-desktop )
grep model.name /proc/cpuinfo model name : Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz
Note that this is a desktop system, not a laptop.
------
I tried however a ubuntu livecd and there i had cpuscaling ( speedsteping ) out of the box
If more info is needed please advise as to what. .....

I don't know if that module should be loaded automatically, but you could add that module to the MODULES_LOADED_ON_BOOT line in /etc/sysconfig/kernel. That willo get it loaded.

Interesting, when i load the module via sysconfig i get this in dmesg
bjolie@embla:~> dmesg | grep CPUFREQ [ 15.968447] CPUFREQ: Per core ondemand sysfs interface is deprecated - up_threshold

( works fine btw )

I'm surprised that message didn't occur when you loaded with modprobe manually. It seems that someone needs to rework that module and change the interface.
As long as it works, no harm - no foul.

It's not from loading the module, it's from using old the sysfs interface to it.
