Heh, I bet. uhci shouldn't be able to be unloaded in that case, I think
usb_get_bus() should increment the bus's module reference count. But
then that would piss off all of the people who like unloading their bus
driver without unloading the device driver first :)
Other than preventing that case, I don't see an easy way of fixing it.
Oh yeah, here's the easy way:
# CONFIG_MODULE_UNLOAD is not set
in the .config file...
