I have installed the 10a432 DVD along with the following kexts:

disabler.kext
dsmos.kext (or whatever it is)
nforceATA.kext
nforceLAN.kext

and using the mach_kernel.432amd that I got somewhere on this forum on my asus m2npv-vm mobo with an AM2 processor

added the EFI string for my 8800gt and enabled quartz gl from osx86 tools.

System profiler does NOT list QE/CI (at all!) which I thought was odd but when I ran Quartz Debug it shows QE enabled.

I have this interface lag that happens whenever i try to move a window or do anything really, and if i try to drag and drop an icon it hangs but I can still move the mouse (cant use keyboard shortcuts or cmd-opt-esc though.) I tried loading Chess to see if it was maybe a problem with OpenGL and it takes forEVER to load or make a move when usually on 10.5 it is lightning-fast. The intro movie from the setup assistant also was very choppy when playing back, i'm assuming its related.

Anyone have any ideas?

Cheers,
Nick

Author Update #1 @nickdanger3d 2009-08-16

The lag happens regardless of the quartzgl setting. I'll try using natit.

Author Update #2 @nickdanger3d 2009-08-16

OK Natit boots and doesn't give the interface lag, but no opengl, qe/ci, or anything like that. Also, it's stuck at 1024x768. Any suggestions while I do more research?

As far as your KP using mach_kernel.432amd, did you try using -x32 as a kernel option?

Author Update #3 @nickdanger3d 2009-08-16

oh wow, as I was typing that reply now i get these strange artifacts... for example, when the cursor blinks i get a horizontal line like a big shadow of the cursor to the left of it... I don't think natit is gonna be the final answer to this issue.

Author Update #4 @nickdanger3d 2009-08-16

Also, can we move that kernel issue to a new thread

Author Update #5 @nickdanger3d 2009-08-18

Status:

I can boot with Natit but get no QE/CI and I'm stuck at 1024x768 (Yuck!) I was reading that you might need to edit the Natit kext but the one I found seems to have different information in the plist.

Is it expected that editing Natit will allow QE/CI to work?

Also, to electro: I'm having trouble understanding your post. Are you saying because I'm using the AMD kernel I can't use efi strings for my GFX card? Leopard runs fine with EFI strings on this same computer. Is there a way to use the vanilla kernel on AMD? I didn't think there was.

Cheers,
Nick

@nickdanger3dadded the EFI string for my 8800gt and enabled quartz gl from osx86 tools.

try without quartzGL

System profiler does NOT list QE/CI (at all!)

that's normal for 10.6

I have this interface lag that happens whenever i try to move a window or do anything really, and if i try to drag and drop an icon it hangs but I can still move the mouse (cant use keyboard shortcuts or cmd-opt-esc though.) I tried loading Chess to see if it was maybe a problem with OpenGL and it takes forEVER to load or make a move…

remove the efi string and try some kexts.
i'm doing fine with natit with my 8800gts e.g.

Field Note #2 @electro 2009-08-16

problem is in kernel for amd is not retail vanila ,
this kernel mach_kernel.432amd is patched

Field Note #3 @maya77 2009-08-16

Where you find 432 kernel?

I have only 394.

And yes, it's recommended to leave QuartzGL OFF.

Field Note #4 @aryajuanda 2009-08-16

i cant run 10.6 with mach_kernel.432amd… its allways KP...

Field Note #5 @pαuℓzurrr. 2009-08-16

Here is the kernel: rapid share.de/files/48107385/mach_432amd.rar.html

Field Note #6 @aryajuanda 2009-08-16

yes i have try -x32 boot option... still got KP on boot

my spec:
AMD Athlon X2 7750 BlackEdition
Gigabyte GA-M720-US3
4 GB kit DDR2 PC 6400 G-Skill BlackEdition
500 Gb Seagate Baracuda SATA
GeForce 9600 GT 512 MB GDDR3 256Bit
Ideneb 1.5.1 + Update 10.5.8 || Windows 7

Field Note #7 @maya77 2009-08-16 ↳ Re: @pαuℓzurrr.
@pαuℓzurrr.Here is the kernel: rapid share.de/files/48107385/mach_432amd.rar.html

Thanks, I've found it in the meantime, but SL won't boot.

Kernel Panic whatever I try:
-x32
-x64
-legacy -f -v -x
arch=x86_64

Always the same KP and "Turn off..." message.
