Help : 'XCPM: P-state table mismatch (error:0x11)'

[Solved]

First of all, My Hackintosh is... : i3 3240, ASUS P8Z77-V, HD 7770 (And Clover + UEFI)

Sleep and other stuff is working without problem. The Last one is speedstep with xcpm.

I created my own ssdt with PikeAplha's script. I put ssdt.aml into /EFI/CLOVER/ACPI/Patched and when I reboot (with -xcpm)..

got this error.

7/23/14 5:29:24.000 PM kernel[0]: IOPPF - Found another boot volume.IOPPF: XCPM mode
7/23/14 5:29:24.000 PM kernel[0]: XCPM: P-state table mismatch (error:0x11)
7/23/14 5:29:24.000 PM kernel[0]: X86PlatformShim::sendPStates - pmCPUControl (XCPMIO_SETPSTATETABLE) returned 0x11
7/23/14 5:29:24.000 PM kernel[0]: X86PlatformShim::start - Failed to send PStates
7/23/14 5:29:24.000 PM kernel[0]: X86PlatformShim::start - Failed to send stepper

I checked other pages about xcpm mismatch but couldn't get how to fix..

Number of P-state using attached ssdt is 4 : (16, 25, 29, 34) (checked with dpcimanager)

I attached a copy of config.plist, ssdt.aml and ioreg.

Please help me for fix this error~

You need to try to drop the OEM SSDT as there might be a conflict.
Add this to your ACPi

<key>SSDT</key>
<dict>
<key>DropOem</key>
<true/>
</dict>

You may also need to use the IvyBridgeWorkarounds described by Pike R. Alpha when creating the SSDT.

Thank you for you reply. I tried DropOem via clover configurator .. but same result.

I checked this articles..

and I thought I need to edit ssdt.aml (bad english; ) but couldn't figure out how to edit.

jesus.. it's so simple;;

I made ssdt with these option and mismatch error has gone.

-w 2 -x 1

(not needed -x 1 if you are on xcpm)

There's still error 'X86PlatformShim::start - Failed to send stepper' but I can handle it.. (maybe...)

Ok, maybe you could try using different SMBIOS in your config.plist. I think your system is trying to load incompatible settings from the IOPlatformPlugin.kext. Try using MacPro3,1 SMBIOS. If the error disappears them we know it is not an SSDT issue.
