0xf00fc7c8

Shouldn't that be 0xc8c70ff0, since we're talking about a little-endian CPU? (according to this[1] the bytes in memory are F0 0F C7 C8).

On the other hand, I probably wouldn't have recognized the F00F bug mention if you had actually written 0xc8c70ff0.

It was a popular meme in computer security focused groups for a while after it was discovered since it was an unprivileged DoS. I only remember seeing it talked about with the f00f representation: some people even called it "getting f00f'd" if you managed to trick someone into executing the instructions.
