First of all, here briefly my machine:

Gigabyte GA-Z68MX-UD2H-B3 (rev. 1.0) BIOS U1f(UEFI BIOS)
32 GB Ram Patriot
Galaxy GTX480OC 1.5 GB

then ssds, hods and a card reader.

I installed Mavericks 10.9.1 using the last release of Unibeast, then rebooted via USB, selecting the freshly installed Mavericks to complete the process with Multibeast. Among the kexts I have selected, the patched AppleIntelCPUPowerManagement, then i5 SSDT.
As for the boot options, I cared to deselect CPU States and I selected DropSSDT. System definition: iMac 12.2

If I try to booth straight from the ssd with Mavericks, I get the well known
P-States Stepper Error 18 at step 2 in context 2 on CPU 1
followed by the AppleIntelCpuPowerManagement Kernel Panic.

I have tried also the system definition MacBookPro 8,1 but it didn't change anything.

Now I am able to use the system booting from the usb stick with Unibeast, however the system sometimes hangs randomly.

I sincerely thank everybody who can give me help to solve this!
