I'll try to install latest 3.9 on the machine this bug occurs and see if I manage to reproduce it. As far as I remember, it happened when I changed some USB 2.0 devices on an USB 3 port. The machine is re-installed and runs F18 now. > Heinz: Sorry I forgot to add you to CC in the first mail, but Sarah fixed it. Never mind, I'm subscribed to lkml and saw the thread there ;-)
