power management may be incomplete or unsupported


Hi everyone, finally I managed to have a successful installation of Niresh's Yosemite Zone 10.10.1 on my AMD configuration with this specs :

Mobo: Asus M5A97 EVO r2.0


GPU: Sapphire Radeon r9 270x vapor x

HDD: Western Digital Caviar Blue 1tb

Ram: 8gb 1600mhz corsair vengeance

I boot with /amd npci=0x2000 -v and the installation has completed successfully but when the PC restarts and when I boot with npci=0x3000, computer shows me a grey screen with an infinite spinning beachball cursor. I can only enter Yosemite in safe mode whit boot flag "-x". I tried lots of boot flags include "GraphicsEnabler=No" and the result is always the same grey screen. I've set the uefi bios disabling Vtd, turning on AHCI and so on without result. When I boot in Verbose mode with bootflag "-v" the black screen with white signs shows me after PCI configuration :

"Warning: IOPlatformPluginUntil : GetCPUIDInfo: this is an unknown CPU model 0x3a
--Power management may be incomplete or unsupported"


Please help me

After booting into Safe Mode, did you use Multibeast for Yosemite? If not, then just use easybeast and restart. See if it fixes the problem.
