I have experienced similar problems with Fedora 6 and 7 although they seemed
to occur only intermittently. I never found a real answer, at least partly
because I could never reproduce the problem at will. I started to suspect
the screen saver and the last time it happened I was able to fix it by
killing the screen saver (via an SSH session from another machine).

I am not offering this as a definitive solution but it might be worth a
look.
