ACPI Kernel Panic on Boot After Clover Update from Yosemite

[realmenfinishlast]

Good morning everyone!

I successfully followed this guide:
http://www.tonymacx86.com/el-capita...rect-update-os-x-el-capitan-using-clover.html

and upgraded my working desktop from Yosemite to El Cap without much trouble at all. I got all the way to step 8 where I should be just booting to the drive where El Cap was just installed too but no matter what I try I get a kernel panic "unable to find driver for this platform: \"ACPI\".../IOPlatformExpert.cpp:1665"

A quick google search shows that this is not an uncommon KP, but the most common causes are a bad DSDT file which I'm not using at all, and to uncheck one of the fixes in the config.plist file for clover. I've tried both the config.plist I was using on Yosemite which did have a few fixes selected, as well as a new config.plist I used when booting to the El Cap installer which removed all of them. I did look in S/L/E and I do not have a kext for "IOPlatformExpert" so I'm not sure if maybe that's all I'm missing or not..

Running a Gigabyte Z68X-UD3H-B3 with most recent UEFI bios (clover was installed UEFI) along with a PNY NVIDIA GeForce GT 640 1 GB video card.

Thanks to anyone who can help!

Same problem.

ACPI kernel panic on boot of 10.11 Works flawlessly on 10.10.5

Specs are as stated in my sig.

Try booting with cpus=1 and see if you get any farther.

Did you guys solve this problem? if so How?

I'm having the exact same problem and my -v screen reads exactly like Op's

I tried adding boot flag cpus=1 as suggested but get same KP.

tks!!

Have you checked that your config.plist is the same as before after updating Clover?

wow...that was a quick reply! ... tks!!

At the moment trying to find the right boot args to get access to the config.plist on my efi partition.

System was working fine until I used clover configurator and obviously set something wrong.

Try booting with -x if you still can't boot then use your Clover Boot stick. Attach EFI below put in a ZIP (Remove theme folder).

This is shot of current KP ... in case you see something obvious before I can give you an answer on my config.plist

Id say Clover Config.plist have changed. You may be better off reinstalling.

here is zip of EFI folder ... sans Themes and Apple directory (doesn't look like that changed and was big directory)

It looks like there is a New Patched ACPI entry ... might be the cause?
