Subject: cat /proc/cpuinfo shows full throttle

I'm confused here
when doing a cat /proc/cpuinfo
with an idle system,
I see cpu MHz at 2167.000;
should be at 1000.00
(when settled down);

the only changes to the system were
compiling xorg from git
which had me running after one dependency to the next.
(I honestly can't remember what xproto thing/whatever
package that might cause this);
any ideas would be appreciated.

In any case the system is idle and quiet.
it just says full throttle when it should say
nice and quiet.

is acpi-cpufreq loaded ? and cpufreq-ondemand ?
(Also make sure the relevant sysfs knobs are set to use ondemand)

If no: Make them so!
If yes: boot with cpufreq.debug=7 and send the dmesg
to [email protected]

Thanks,

Dave

I've managed to have cat /proc/cpuinfo
read correctly. somewhere somehow
when compiling xserver I Installed
some package that messed up libpowersaved11
and liblazy1. reinstalling those packages as well
as the other powersaved packages seems to have resolved this
issue for me.(as well as haveing cpufreq running correctly);

I just can't remember what might the package be that
caused this to go crazy.(oh-well);
as long as the fans aren't screaming/or stuck I'm happy...
