Fedora 17 Crashes on fresh install

[Jim]

F17 / KDE

It will crash when trying install.

It will crash when your trying do yum update.

There is no pattern as to when it will crash.

When the crash happens it takes you back to a black screen with a lot of 
white print.

Below is the last three lines of crash when I was trying to do a yum update
