How to Restart Your MacBook From a Kernel Panic
A kernel panic on a MacBook occurs when the kernel of the Mac OS X operating system receives an unexpected instruction or handles an instruction improperly. A kernel panic is a serious event, and you should approach it with concern that the computer may be failing. A Mac kernel panic is the equivalent of a Windows blue screen. Kernel panics can be caused by damaged or incompatible software or hardware. You will recognize a kernel panic if you see a notice, "You need to restart your computer," followed by further instructions.

Make a note of what took place just before the system halt. Write it down or make a mental note. If the problem persists, it will help to diagnose the issue if you note what may have caused it. Note any applications that were open, and which was active when the system hung.

Reboot your MacBook by holding down the power button until it powers off, and then pressing the power button to power it on. This is the only thing you can do after a kernel panic.

Anticipate a recurring kernel panic. The cause of these panics can be either software or hardware. Be ready for the problem to happen again. Panics caused by hardware are most likely to recur.
-
4
Attempt to recreate the panic conditions. If the panic does not immediately recur, consult your notes and open the same applications that caused the initial panic. If you can replicate a problem, you can receive support for it.

5
If the panic does recur, boot to your Mac OS X Install Disc, and run the Apple Hardware Test. Insert the appropriate disc in your optical drive, and hold the "D" key on your keyboard as you restart your MacBook. Prior to OS 10.5.4, the hardware test was on Disc 1, and for later versions it is on Disc 2.

Tips & Warnings
If you are within your warranty or have an AppleCare extended warranty, call AppleCare and log the event in the Apple support database. This will help establish a record that the problem began while your MacBook was still in warranty, even if you can't immediately duplicate it.
Backup all important data on your MacBook to an external location at the first sign of a kernel panic. If the system needs to be sent in for repair, you may be without your data. In the worst case scenario, a kernel panic could lead to data corruption or loss.
