The best? It is complicated, the way to get this is to set up a serial 
console to another machine so you can catch the output of the panic 
message. A simpler one is to get a camera and take a picture :-) I'll do 
that on Monday with my test laptop.

At least it is something repeatable so there's a good chance we could 
get it fixed (unless it is an interaction with the extra Fedora patches 
that are part of the build).
