D620 - Mountain Lion - C-state power management not initialized?

Hi there. I'm trying to install on the Intel model (not Nvidia), Mountain Lion from myHack 3.31 and I boot with -v, and the installer freezes (by freezes I mean I can't press a key to display those weird characters) saying:

 

ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized.

 

I can't see an option to enable something like that in my BIOS, so I'm absolutely clueless at what to do. Would anybody be able to help me out please?
 

Many thanks in advance,

Nick :)

Bro, I've tried that. Still getting the same 

ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized.

error.

That error will not cause any system freeze or prevent the OS from booting to completion. It's related to CPU Power Management, meaning CPU management won't be optimum (C states are CPU power modes from max voltage at full power to low-power in sleep mode. You can read about this here), but system will remain fully useable nevertheless. My own D620 GMA950 does display that error just before switching to ML desktop but there's no issue running ML at all...
 
Granted that I have not retested the process with myHack v3.3.1 (and I see no reason to believe it would differ from previous versions) but if you follow the described process rigorously, I can guarantee that you will obtain a fully running ML installation on your D620. Recommended BIOS settings are also provided in this very section, so if you've followed that as well, you should not have any issues at all.
