I have some problems sinc FC3test2. With every kernel since test2 sometimes laptop plugged to AC outlet or battery supplied turns off. It works at random times, but today, after upgrading to 2.6.9-1.681_FC3 the laptop turned off 4 times in 1 hour. It is too much. I've just been working in gnome (configuring sound or network) when it took place. How to fight this? I have now FC3 final (clean install). Darek Borkowski
