Install crash - "kernel panic"

I'm trying to install FC4 on a Dell laptop. I have used this same media to install to a generic x86 desktop with no issues, however when I attempt to boot the first disk on the laptop it says,

switch root mount failed /22
Kernel Panic not synching : Attempting to kill INIT

I've searched all over and this seems to be a pretty common error but all the examples I've found are post install. What could be causing this on a first boot from an install CD?

I'm not sure how the drive is partitioned as I just got it, but it wouldn't surprise me if it was a single NTFS partition. Could this be the problem? I'm not sure how I could delete it if I can't boot it to a CD.

The drive shouldn't be the problem. Try passing the options 'noapic nolapic' to the kernel when booting.

What would I be doing here, disabling power management? How exactly do I pass these. I tried just entering this at the first boot prompt and it didn't know what I was trying to do, which isn't suprising since I didn't really know what I was trying to do.:confused:

Okay, it appears that the proper directive is 'acpi=off'. However this has not changed the behavior at all. If anyone has any other suggestions, I'd certainly appreciate it. I think I'll cross post this over on the laptops forum since this is probably a laptop issue.

acpi is NOT the same thing as apic, despite the similarity in acronyms. acpi is a "Advanced Configuration and Power Interface". The main thing I know of that it controls is powersaving modes on newer motherboards. apic is "Advanced Programmable Interrupt Controller". I'm a little vague about what it does, but it may help in this case, it fixed some problems I had when installing Ubuntu on my computer at work. Can't remember what the exact command in Fedora is, but you probably want to type something like "linux noapic nolapic" at the boot prompt.
