I do not know why but it starts the kernel in 32bit

How is it possible if ML kernel is x86_64 only?

Run uname -v in terminal.

I do not know what is going on so I can not use kernel cache.

It's 64 bit.

Me neither. Do you get any error messages? Type Wait=yes -v at boot.

when I use this command,and boot with -v UseKernelCache=Yes works.

sudo kextcache -v 1 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext -z /System/Library/Extensions/

 

sudo kextcache -system-prelinked-kernel -all-loaded

but every time I install a new kext must be entered again.

other, there's a solution for this?

Extensions.mkext is not kernelcache.

You have to set UseKernelCache=yes in Boot.plist to use kernelcache.

[crunk]

is already there

But does not work

Here's a photo where it stops

I'm not the expert bro but I've had the same “Still waiting for root device” problem...

Boot with USBBusFix=Yes (that fixed my problem) and of course, ensure SATA devices are configured to run in AHCI mode

IOAHCIFamily.kext

AppleAHCIPort.kext

thanks for the reply.

the patch worked

thanks

[Irish_Man]

well....the patch is probably .plist file

Open Terminal , and type one of the commands depending on where your kext is. /Extra/Extensions or /System/Library/Extensions....

for /Extra/Extensions type sudo nano /System/Library/Extensions/[YOURDRIVE].kext/Contents/Info.plist

for /System/Library/Extensions type sudo nano /Extra/Extensions/[YOURDRIVE].kext/Contents/Info.plist

If you need to patch a plugin inside a kext, type like this:

sudo nano /System/Library/Extensions/[yourdriverhere].kext/Contents/PlugIns/[yourplugin].kext/Contents/Info.plist

sudo nano /Extra/Extensions/[yourdriverhere].kext/Contents/PlugIns/[yourplugin].kext/Contents/Info.plist

Actually it's a binary patch, it adds a 200 ms delay in kext start.
