Hi, Same problem here. Lion 10.7.4 and Mountain Lion DP 1 booting fine with all hardware support but Mountain Lion GM freeze after '[IOBluetoothHCIController] [start] -- Completed'. I already tried removing bluetooth kext but still its same, not booting except safe mode.

What kind of graphics do you have?
If you miss the kexts for your graphics card, then it won't boot.
In safe mode it will only load the necessary kexts, which will make you boot properly

Have had the same issue in DP4 and GM - copied over nvidia graphics driver from DP3 did the job for me.
No solution though, just a quick dirty fix

Had the same problem; it's graphics-related.
You could use osx86 tools to create a custom EFI string, then paste it into your chameleon preferences using the chameleon wizard. It worked for my geforce 550ti, although it's only a partials solution.

For me it was NVDAHal50.kext that was causing boot problem, adding my device id solved it, now it's working fine.

Solved: replace kexts in /System/Library/Extensions starting with NV with the ones from the file below.
Best practice is to delete them and use kext utility to drop these in.

Hi bilalbg et al.
I've got Mountain Lion working now with a 9400gt card. Problem is I deleted and replaced the files so many times, i'm not really sure if they are the Lion or ML files now lol... in any case, if you haven't got it working yet i can explain, just haven't figured out yet how to attach the files
Worked it out
So the files included are in fact the ML files, not the Lion files, with the exception of the NV Enabler. So it's the NVEnabler and the EFI string that's making it work.

Same now on my other partition, after upgrading to 10.7.5...
They have in common:
[AGPM Controller] unknownPlatform
Deleted /System/Library/Extensions/AppleGraphicsPowerManagement.kext
The AGPM message is gone, still no UI

So, same GPU than I have. Really strange. There is nothing special about that NVS series...
