Please see above. In the problematic case, the linux kernel and the
BIOS detect the floppy *controller*, and thus think that a floppy is
present. This seems to be the case with a lot of motherboards, which
have a floppy controller, but no drive attached to it. Then, if you
try to speak to the floppy through the controller, you get the long
timeouts.

If there is an actual floppy drive, there is no problem.
