strange thing about extension.mkext cache and boot

[Guest the tourist]

Guys there's something I cannot understand: I rebuilt my system extensions cached after repairing permissions. When I go to boot my system it hangs on "still waiting for root device". If I delete the file, the booting process runs smooth with no interruption.

Where's the fail?

You are on Lion,right?

try this:

<key>UseKernelCache</key>

<string>Yes</string>

Exactly

 

try this:

<key>UseKernelCache</key>

<string>Yes</string>

 

I did that and it caused me the root device error

UseKernelCache=Yes uses the new cache mechanism and does not use the Extensions.mkext file,i wrote about it in the Technical FAQ subforum.Also,when you use that flag,only the kexts in /System/Library/Extensions that are also in the rebuilt kernel cache are used.So,do not use .mkext , move all extensions from /Extra/Extensions to /S/L/E ,set the permissions and rebuild the cache with :

sudo kextcache -system-prelinked-kernel

sudo kextcache -system-caches

 

And you are good to go.

I did everything but it doesn't change anything: it reads every single kext

Maybe there's something wrong with your org.chameleon.Boot.plist. Try typing UseKernelCache=y -v at the Chameleon boot prompt. If it works this way, then check your boot.plist.

String error. Everything now it's ok. TY to everyone.

Glad it worked out for you.
