I have Mountain Lion installed, and it works fine, except when I boot, I have to use KernelCache=No, or else I get "still waiting for root device"

I've seen this before, but never solved by not using caches. Any ideas as to what I need to do?

This may be too obvious, but don't keep anything in an Extra/Extensions folder.  Using kernel cache bypasses E/E.

[jazzyguy]

Yeah that much I know.

Today, I try to install to another machine, to duplicate problem of UserKernelCache=Yes on my other machine.

Configuration of this machine: Dell 530 - Core2Quad 6600 - 3Gb DDR2 667Mhz - Nvidia 8800 GT Apple version.

Install 10.8 as usual but I need to copy IOATAFamily.kext from 10.6.x, sucessfull.

Boot 10.8 with UseKernelCache=Yes My screen display this:
.....Loading Darwin 10.8
.....Loading kernel cache /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache
.....Read HFS+ file:  [hd(0,2)/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache] 4096 bytes.
.....Can't find
.....Press a key to continue....

As you see, it's not give me "still waiting for root device" . Hit any key still get that error can't find kernelcache (I do have that kernelcache).

So boot with UseKernelCache=No, everything fine.  I think we need a new chameleon boot for darwin 10.8

[jazzyguy]

Others boot with kernel cache fine.

Maybe You need to remove cache. since you changed IOATAFamily.kext.

Same me and I boot UseKernelCache=No and re install any kext Use Kextwizza it ok. I think if I install program e.i Paragon NTFS, Mountion Lion make Kernelcache size 10,2Mb, when Ketxwizza make Kernelcache 30,2M. It's diffirent? thanks

I haven't changed it.

[kdtt]

Well,then you might have extra folder.if so ,delete those kexts if you can boot into os without it.
If that doesn't work ,change chameleon version.because with my experience,some chameleon doesn't load extra folder kexts even
though they read the kexts.

[jazzyguy]

I don't have any extensions in my extra folder.

[kdtt]

You have all kexts in s/l/e.
Do you have icon fix kext?
if so, remove that kext and cache or disable hot plug option in bios if your bios have one.

No I don't have that kext.

And I don't have hot plug in my BIOS.

[kdtt]

I used to have that problem and that's what i did to solve.
You have all grey icons execept ide hds.
what is your hd? wd, seagate,samsung?

[jazzyguy]

idk. Its a typical hard drive. Works fine in Lion.

ML doesn't like x32 (chameleon issue on ML), it will give you that error. Boot x64 to fix it

[cochon]

thanks, I got it

[jazzyguy]

What do you mean?

I want to use full 64 bit since I can support it.

[robla]

It might have something to do with your install. You must copy kernelcache from 'Mac Osx Install ESD' to 'Mac Osx Install Base'  before installing.
