Just to update everyone a little bit. I've got the ALC892 on my E767 working with AppleHDA now using the new ALC8xxHDA kext from MacMan over at tonymacx86. First I tried to bin patch AppleHDA from 885 to 892, which made it load, but didn't give me sound. Then I switched to the 10.6.2 AppleHDA rollback and now it works.

So, that's a step forward. Almost there.

Still no ability to load AppleCPUPM without the type 13 panic, so no speedstep either. I've been playing with acpiexec to see if I can find something in there, but I don't really get it yet.

Here's my DSDT with the necessary HDEF section for the ALC8xxHDA to work.

Alright, so can someone like airwalk667 or msinfo pleeease make a full acpidump from linux on your X58 SLI and post it? You've got to be using the same bios version (SZ2Z) and settings you're using in OS X. I want to get the whole thing and compare it to my full dump from my X58 SLI3 to find all the differences I can in the acpi table and see if maybe something in there is causing the panic. It's a race to see if newegg has an open box ASUS P6T6 before I make this work.

kernel panic
 

Wow this thread is so huge! I first installed with iBoot + Multibeast and I got a working system. Next, I followed the guide on page 1 exactly along with ALL of the important notes at the bottom. I'm getting a kernel panic when I use the /Extra folder from this guide. When I use my backup /Extra folder I'm ok. I was wondering if I list what I have in there maybe someone could help me figure it out.

Backup /Extra folder that works kexts:

EvOreboot
fakesmc
JMicron36xATA
JMicron36xSATA
LegacyAppleRTC
NullCPUPowerManagement

Airwalk's Extra folder kexts including suggestions at the bottom of post 1:

AHCIPortInjector
fakesmc
HDAEnabler
IOAHCIBlockStorageInjector
JMicronATA
LegacyHDA
NullCPUPowerManagement
OpenHalfRestart
PlatformUUID
SleepEnabler

dsdt.aml that I made myself

Here is a photo of my kernel panic:

@neptunet, I suspect sleepenabler. Try booting without it. What board do you have and what bios version?

So my FTW3 started having all sorts of problems mid-December, right when I was going to start honing the DSDT to get things finalized. Getting it replaced was no easy feat, but I finally have a new, working board and it's time to start over. Hopefully I'll have some good news to report herein the next couple of days.

then again..
 

@banini_jeque I have the EVGA X58 SLI, the original one. Also how do I find out what bios version I have? I checked eleet but it didn't say. Also I am having another issue - I went back to my backup Extra folder and my system is hanging now before I get to OS X. I booted in verbose mode and took a screenshot where it hung up.

@farski, are you going to try to get speedstep working? We need to identify a difference between bios versions e758_sz2z and e758_44 that is causing AppleCPUPM to panic, despite our setups meeting it's requirements otherwise. Not sure how to figure that out. Then if we manage that, we have to see if we can do some sort of override, assuming that the cause is the same across all post version 44 evga x58 bioses.

@neptunet, you probably don't have your DSDT quite right. The hangup is probably related to the AppleRTC errors you're getting, so look at your RTC device in your DSDT and compare it other peoples. It should say what bios version you have on the bios boot screen, or on one of the bios setup screens.

@banini_jeque i removed the DSDT.aml from both directories before i took the screenshot.. what do you think of that? do i just need to reinstall?

No, you need to have a modded DSDT, it just needs to be done right. If you're new to this stuff, I'd say use airwwalk's extra folder with his DSDT in it, but delete SleepEnabler. I think SleepEnabler was causing your original issue, and not having a DSDT the second one. Then if you find out your bios version, if it's sz2z you can also delete NullCPUPM and OpenHaltRestart and you should still be able to boot.

@banini hey I went back to my airwalk extra (without the sleepenabler - well I changed the .kext extension but I left it in there) and dsdt but I got the kp I first posted. My bios is sz50. I guess my bios is newer - what do you think of that?

EDIT: dang banini_jeque you did it! i made some edits to the airwalk extra folder - so i dropped in the original folder but put in my custom boot.plist and I booted! Wow.. what a relief to be back in my installation. Thanks for the suggestion. Now I just need to get sound working I guess and then start seeing if anything else is broken. What puzzles me is that originally I had no DSDT or airwalk Extra folder but now my system won't boot up without it! I have no idea what I did. Haha.. I'm so lost. well at least for the moment I have something to fall back on. I guess I'll copy /Extra and make changes one at a time to keep track of what I do.

About the DSDT.. I booted using airwalk's DSDT and I did not get the CMOS reset, so that's good! BUT, I noticed when I decompiled his DSDT that it only has a single entry for RTC length - whereas when I make my own DSDT and decompile it, it comes with 2 RTC length entries in two different headings - not the single "CMS" deal. What is that all about? Is it relevant?
