NetBSD
>Environment:
NetBSD/acorn32 version 1.6-release but also in NetBSD-1.6D
Architecture: arm
Machine: acorn32
>Description:
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
same.
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.
>How-To-Repeat:
just execute `fdformat fd0' or `disklabel fd0'
>Fix:
NONE known... only just dont use the floppy in this way :(
