test13-pre6 -- OOPS at boot time in kmem_cache_create (usb-ohci related)

From: Miles Lane (miles@megapathdsl.net)

This OOPS occured at boot time when I did not have my Belkin
BusPort Mobile USB host-controller inserted. /etc/usb/rc.usb
tried loading usb-ohci. After the boot process completed
(after the OOPS occured), I was unable to unload the module
and lsmod showed that usb-ohci was still initializing.
Presumably, it got wedged when the OOPS occured?
