slack 11 + Core Duo T2600 + cpufreqd2.20 = variable frequency for 1 cpu only?
Hi there!
I am using a Dell m90 with a Intel 2600 (Intel Core Duo 2.1Ghz) processor. I installed cpufreqd-2.2.0 and cpufrequtils-002 on a brand new Slackware 11 with kernel 2.6.17.13 and I can monitor my CPUs (core duo=2 cpus) speed in KDE. All that is working great.
I can customize the rules in cpufreqd.conf and they got reconized well. Simple and excellent.
But.. wait, only ONE of the two processors gets is frequency changed by cpufreqd.
If I do:
(launching in foreground, maximum verbosity), I get upon event (for instance plugging AC cable):
...

cpufreqd_set_profile : Couldn't set profile "HPerf" set for cpu0
cpufreqd_loop : Cannot set policy, Rule unchanged ("none").

Yes! only cpu1 has its frequency changed! This is confirmed by the KDE system monitor applet and a (the lines 'cpu Mhz' is different for each proc):

I am kind of puzzuled here; I do not know where to look to debug this...
Any ideas anyone?
Thanks,
Patrick
