NetBSD/acorn32 version 1.6-release but also in NetBSD-1.6D

Architecture: arm
Machine: acorn32
Due to a fault of unknown cause a reference to the /dev/rfd0a device causes 
the machine either to hang, coredump, coredump the program, exiting shells, 
etc. when `fdformat fd0' is executed but also when `disklabel fd0' does the 

At times a process will be coredumping and the process be stuck on wchan
`closef' with status DEL+.

A simple `dd if=/netbsd of=/dev/fd0a' works fine regardless of the 
blocksize specified.

just execute `fdformat fd0' or `disklabel fd0'

NONE known... only just dont use the floppy in this way :(
