OKi some clarification.
Yum not working I figured was simply the service beeing down, nothing worse it shows. Get the listings now when I do a yum command. Guess I am at only the dvd rw drive gone. I used the software updater from fedora menu's when I updated. All default, beeing a linux noob i don't even understad what repositories are so I couldn't answer you
But it's a default Fedora 6 installation if that helps you understanding.
I tried to boot old kernel but no luck. Think I have done 2 updates though before I noticed dvd drive gone (not used so much).
