To make it easier for me to keep track of bugs, I have closed all previous bug reports, as code is changed.
The release version has got two error messages for the log:
VoodooPowerMini: Failed to read CPU load on
This means that it can't connect to the IOCPU. If you see this VoodooPowerMini is loaded prematurely. If this is a common problem I will add a new "reinitializing" of the kext in next version.
VoodooPowerMini: Failed to get full power management control of CPU
If there are other factors influencing CPU power state, you will see this. And basically it is caused by other speedstepping functions working along with VoodooPowerMini.
