EDIT: The only difference I found is I drop all SSDT tables in new config, while only dropping CPU SSDT tables in my old config. Interesting, because it works in my laptop.
Btw, because the problem is in my config.plist, so you can try latest Clover. It won't make any difference at all.
EDIT: Can you install DPCI Manager, run Pstates and post your Pstates log here? I thought Ultrabook CPU can't be used with Macbook Pro 9,2 SMBIOS?
