We corrected the issue Naquaada talks about above while in the IRC channel but I figured we would add it here too. In your case you have an nForce 570 chipset which is the same as mine. I was able to use Slashacks 64bit modified kexts to prevent freezing.

64Bit AppleNforceATA.kext:

1. Remove /System/Library/Extensions/AppleNForceATA.kext if it exists
2. Copy AppleNForceATA.kext to /System/Library/Extensions
3. Entered your admin password when prompted
4. In Terminal write:
Code:
sudo chown -R root:wheel /System/Library/Extensions/AppleNForceATA.kext
sudo rm -R /System/Library/Extensions.kextcache
sudo rm -R /System/Library/Extensions.mkext
5. Restart using the boot flags:
Sometimes Extensions.kextcache is not there. This isn't an issue. What we are trying to do is make 100% for sure that the cache is recreated with the new kexts. So basically we are deleting the cache and then booting with -f to force OSX to pull from the Extensions Folder
If your still having problems you can repair disk permissions in Disk Utility or by using Terminal with the following:
Code:
sudo diskutil repairPermissions /
This method can be used to install any kext you want. When installing homebrew kexts repairPermissions will make no difference as OSX wouldn't know the proper permissions to assign.
