The fix for me was to simply delete the power profile from my MacBook model in a kext config directory. Everything was fine until I upgraded to 10.8.5, and then to my system would not boot at all – feeling with the kernel panic very early in booth that had something to do with AppleIntelCpuPowerManagement.kext.
I completely reinstalled and install Mavericks, and then repeated the original fix. It worked fine and my system is doing great running Mavericks.
Uh, "feeling with the kernel panic very early in booth" meaning, boot failed with a kernel panic.
I was kind of confused by what I read about power management having been changed in Mavericks, but it turned out that whatever is relevant to this issue has not changed. As I noted the same solution fixed the same problem.
