Kernel Panic after booting from a superduper drive
At first i copied my internal HD of my Macbook Pro to an external Drive with superduper.

After Booting from this external drive i got an Kernel Panic.

panic(CPUU 0 caller ....): Unable to find driver for this platform: "ACPI".

What can i do ?

This typically means that you're starting up a different Mac with a version of the OS that's not compatible with it...

Booting on the same machine
Thanks for the fast reply.
I am booting from the same machine, but i get everytime this Kernel Panik. Do you have another idea ?

That seems weird. Well... you can try rebuilding your kernel extension cache.

From the original volume, open terminal. Then, type:


sudo kextcache -f -u "/Volumes/your-external-drive"
Press Return, enter your password when prompted (it won't echo to the screen) and press Return again. Then, try starting from the copy.

I got the the folowing message:

kextcache: /Volumes/digitaldrive120: couldn't get Apple_Boot information

What kind of drive is this (brand/model), and how is it partitioned?

Hussein 10-30-2007 11:38 AM

I think i should buy a newer HD.

dnanian 10-30-2007 11:39 AM

How is it partitioned? (What scheme?) It should be "GUID" for an InteL mac...

Hussein 10-30-2007 11:55 AM

Yes, thats it.

The drive is partionate with an Apple Partion Map. I will repartion the drive with GUID Partion Table.

Thank a lot for your superb help.
