P8P67 shutdown with unwanted poweron

First of all sorry for my bad English.

I've got the same problem with two machines on P8P67 rev.3.1. I solved this trouble by removing USB3.0 LaCie driver that I've installed before - PXHCD.kext. This kext is working fine on P8P67 rev.3.0 and has some problems with power management on rev.3.1. I've tried to use also PXHCD from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] installer package (it has some differences), but still had unwanted power-on. And without PXHCD.kext all working fine even sleep (with PXHCD computer goes to sleep only from second attempt).

Yes, it's nice :) but how about USB3 support? I think it is not very important yet but soon it will be more devices with USB3 interface. I hope ours gurus will make new version of this driver as soon as possible ;)

I can confirm, that removing the PXHCD.kext extensions solves this problem for me. Great news! Thx for finding this out :huh:

Hi guys, p8p67 le user here too. Having the same shutdown issue, gonna try removing that kext. Good news indeed.

On a side note did you patched the bios to have speedstep natively? (without the need to patch AICPUPM.kex). Either way do you have in verbose mode

I'm using a patched bios and stock AICPUPM.kext. I don't get that error messages (DSMOS has arrived - is a message which is normal though). I also needed to add the processor scopes to the dst, but i don't use pregenerated C & P states but a custom ssdt.aml afair ...

I am having the same issue with my Hackintosh running High Sierra on P8P67 Pro Rev3.0. Has anyone another solution than removing PXHCD.kext as I don't have it in my extensions folder.

Solved it by deactivating "FixShutdown" in Clover settings "Acpi"->"DSDT"->"Fixes". Found the solution here: https://www.tonymacx86.com/threads/solved-shutdown-and-after-restart-asrock-z97-extreme-6.247353/#post-1706656

Now after activating USB3 using GenericUSBXHCI.kext the unwanted reboot is back again. I opened an issue in RehabMan's repo, but got the answer that no one is maintaining the kext: Link.

This is sad, as USB3 is working as it should, except the unwanted poweron after shutdown. So any suggestions on this? I tried PXHCD.kext with my P8P67 rev.3.0 without success.
