In most cases, kernel panics are not caused by an issue with your Mac. They are most likely caused by an issue external to your Mac. If the kernel panic doesn't happen again within a few weeks, you don't need to troubleshoot further.
It's called a Kernel Panic. Have you installed anything new on your computer like new RAM? If not, do you have all updates installed? What version of OS X are you running?
Try downloading the EFI update and follow the instructions to install it. It may be a little different than Software Update installations. If you keep seeing kernel panics, give Apple a call or visit the Apple Store to see if they can help.
