This corresponds to the following BUG_ON
static inline struct device_driver * get_driver(struct device_driver * drv)
{
BUG_ON(!atomic_read(&drv->refcount));
atomic_inc(&drv->refcount);
return drv;
}
So apparently the module initialization there is
broken in the case of a box without a serial port at all on it.
