Depends on the hardware. Maybe it's a silent failure (as with
CardBus reads returning all ones); or a message passing error that
the driver sees; or maybe the lack of handshake means a bus error
gets generated, and the driver oopses. That last is unfriendly,
enough so that I think nobody would design a "hotpluggable" bus
where hardware behaves like that.
