I've seen this problem repeatedly on my system.  It seems to have
something to do with the automatic format recognition (360K/1.2M) code.
My current workaround is to `od /dev/rdsk/f0q15dt' - use the device
name that explicitly matches the floppy format.  Once the system
has been forcibly told what density/format the floppy is, it seems
to work correctly until shutdown.  It also seems to correctly auto
detect format on subsequent floppies.

I hope this information is useful to someone.
