Hi,

after weeks of trying to get Snow Leopard working on my system I realized that I need help.

First my systems hardware:

CPU: AMD Opteron 142
Mainboard: Asrock 939SLI32-eSATA2
Chipset driver is AppleVIAATA.kext (Attached HDDs are IDE)
Gfx-Card: PoV nVidia GeForce 7900 GT/GTO (GT) (Device ID: 0x029110de)

Software: Snow Leopard 10.6.2 (now 10.6.3)

My problem:

Installing the system works great, everything is supported as it is on Leopard 10.5.8. Now when I install _any_ nVidia injector I get fully working resolutions, QE enabled (depends on the injector) and it looks like everything's just fine.. BUT its not. Actually the whole system becomes unresponsive, animations are slow etc. and the mouse is really really fast.. even with 400 dpi its like jumping from one side of the monitor to the other when I move the mouse like 2 mm.

I can remember having a similar problem with 10.5.6 but there it was the other way around: Slow animations and really really slow mouse (every 20 sec a mouse movement.. :S). I fixed that one by applying a ACPI-fix (not sure which kexts are replaced.. but I'll look into that if necessary).

When I delete the injector kext the system runs great again on low resolution and the mouse is good as well.

I've done a dmesg while running NVenabler (but its the same with any other injector):

"IOHIDSystem::relativePointerEventGated: VBL too high (many numbers), capping to 20000000"

I guess thats just the result of the mouse moving so fast.. not the main problem here.

What I've tried so far:

- Replacing gfx-kexts with the one from 10.5.6 (GeForce.kext, NVDANV40HAL.kext, NVDAResman.kext and the GeForce7x*.bundle)
- Different Kernel 10.0.0 on 10.6.0 system (so without updates of any kind)
- Many other things I can't remember now.. sorry

What I'll try next:

- installing yet another kernel for 10.6.3 which would also include a update from 10.6.2 to 10.6.3
- Removing any PCI Device from my computer (like X-Fi extreme music) to check if there are any conflicts with pci resources
- checking the contents of the above mentioned ACPI-fix which I've applied on my 10.5.6 system
- Installing OS X myself without certain pre-configured distros -> installed with my own retail version: same error


Well thats it from my side.. I'm running out of ideas now so I hope that you might be able to help me with that thanks.

Update: After I crashed my running 10.5.8 system I'll cease experiments until I find a good idea.. thank god I had a Time Machine backup.. I'll guess that my either my mainboard or my gfx-card (or both ^^) is not compatible with snow leopard.


Akii

I have this EXACT SAME PROBLEM. Are there any responses to how to fix this?!
