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?

This BUG() probably means you need to enable DEBUG in mm/slab.c
before you try have OHCI use slab poisoning.
Enable both, or neither, and all should be fine.
