Hi, I have a santa rosa based laptop ( Fujitsu T4220 convertible ) with
at 2GHz processor. In Fedora 8 (and the latest Ubuntu, Mandriva, and
Suse distros) the processor is permanently stuck at 800MHz. Trying to
manually change the frequency and governor using cpufreq-selector and
echoing values in /sys does nothing.
An interesting thing that I noticed is that the frequency scaling does
work for a few minutes after the laptop wakes from sleep, and then goes
back to not working.
I've run out of things to try and I can't figure out if it is a bug or
something I am doing wrong.
Has anyone encountered this or have any ideas?
Thanks,

One thing I noticed is that I have to load the acpi-cpufreq module
in order for it to work on my Toshiba. Figuring out why and filing a
bug report is on my todo list, but will probably have to wait until
I update to F8.

Thanks for the idea, but running ' /sbin/lsmod | grep cpu' gives me this:
cpufreq_ondemand 10317 1
acpi_cpufreq 12365 2
so acpi_cpufreq is loaded. I may need something else loaded, but not
that I can find out.
Another thing I noticed is that on boot it says cpuspeed starts fine,
but after stopping it and running '/usr/sbin/cpuspeed' I get this:
# /usr/sbin/cpuspeed
Error: No speed steps could be determined!
Error: No speed steps could be determined!
That might be a problem...
