"feisty fawn keeps freezing on me, at first i thought it was FF causeing the
issue. But now i have tried opera and it still happens, at random. Mostly
when it freezes i can still move the mouse, but thats it. Today it froze
with the screen saver (gnome feet). How can i tell what is causing this?
would it be in the system logs? i can't take it much longer"
