Subject2.5.10: 2 OOPs - "BUG at usb.c" and "unable to handle kernel paging request"
Hi, I'm not subscribed - please CC me in any replies.

Two OOps when running 2.5.10, as attached. With attatched config.

First occurs on boot, but doesn't stop the whole system. The second
occurs as I was rebooting - see the attached log to see where they

Any more info required? Just ask.
