Thats because the scheduled work became empty before it was executed. -- BUG_ON(!list_empty(&work->entry)); -- Looks like someone forgot to flush_scheduled_work() before exiting. Can you try putting flush_scheduled_work() as the first line in cp2101_exit and whatever is the exit function of io_edgeport? Just a wild guess. Things might be more complicated than this, but no harm in trying.
