I know this doesn't make sense on the surface, but bear with me for a minute. I've got a Thinkpad W530 laptop. The first OS was Fedora 17 and it was perfectly stable. By coincidence or not, when I installed Fedora 18, it started crashing sporadically. This remained to this day on Fedora 19. I've finally narrowed it down to an unlikely source; USB 3. If I don't use the USB 3 ports, the system goes weeks without crashing. However, when I try to use the USB 3 ports, within a short time Gnome locks up. The mouse usually moves still, but I can't interact with anything on the screen. I can't alt + tab, alt + tilda, corner bump or anything else. I can ctrl + alt + fX to get to a terminal and kill the GUI. In a couple of occasions, if I leave it long enough, the windows would start responding to a limited amount, but they would all be jammed up to the top-left corner, have no windows and can't be moved or given focus (so I can only interact with the windows I can see part of). I can't imagine why USB 3 would effect this, but there you go. Any advice on debugging?
