: Interestingly enough, removing the PCMCIA floppy then fully destroyed
: the device -- even if the driver has been kldunloaded already before.

The detach routine is required to remove all resources that the device
used, including disk instances.  When the device is gone, it is gone
and the dangling pointers and such must be cleaned up.  It looks like
fd_detach is doing the right thing now, but I didn't look closely.  If
you are still seeing things in devinfo, then it is doing things
wrong.

If you kldunloaded the device, and the device didn't detach, something
is seriously wrong.

I'm having trouble understanding what you are saying here, so if it
sounds like I'm replying to something you aren't seeing, please
clarify what's going on.
