No, this is not the i586 problem :-)
I just upgraded my ThinkPad T60p to FC6 and I'm under the impression that the core duo isn't handled as good as in FC5. When starting cpuspeed it doesn't go into daemon mode but instead loads the cpufreq_ondemand module. The CPU scaling applets can be loaded in the tray and configured for CPU0 and CPU1 but changing the frequency for one CPU results in a parallel change for the other. This is also the case when the system is under load, the applets always show the same freq for both cores. This behavior is different from the behavior in FC5, where sometimes only one CPU was under load. As a side effect, I think the fan is running more often and at a higher speed as before.
Is there something I must configure, or should I build a custom SMP kernel?
