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.
