Since I have not been able to capture the output of the panics, I don't know if 
it fails in the same place every time. That was intended to be one of my 
questions. How do I capture the panic output? When it just freezes, how do I 
find info on why?

Yes, I tried Fedora 13 first. When I ran into the problems, I tried Fedora 12. 
When I experienced the same freezes and panics, I decided it was not version 
specific.

Thanks. Please keep the questions coming.
