I'm tried updating my MacBook Pro to Mountain Lion. I download the installer, and run it. Then after the reboot, it is suppose to start up with the installation procedure. However at the grey Apple logo screen the computer will kernel panic (with the whole hard shutdown message).

At first I suspected a corrupt installer, so I redownloaded the file. Didn't work still. Then I made an appointment with Apple and they upgrade my computer with their in-store copy.

Well the issue is I have a couple Macs, so it doesn't make sense for me to take every computer in to upgrade. Right now I'm trying my MacBook Air and it has the same issue.

Anyone have suggestions?

Have you tried putting the InstallESD.dmg image that comes with the Mountain Lion installer on a thumb-drive and booting from it? I would normally suspect hard drive failure or memory failure, but since you're having the same issue on multiple machines this can safely be ruled out IMO.
