Description tihor 1997-01-27 00:40:01 UTC
Occasionally using dd to write an image to a floppy dies (floppy light doesnt
come on, kill -9 fails to kill it).  This occurred when comparing write times
for various bs arguments to dd.

How-To-Repeat: 	time dd if=image of=/dev/fd0 bs=4096
	this will occasionally die without warning.

Please, log into another terminal on that machine, and see on which
event the process is waiting (_before_ trying to kill it).  You can
see this in the WCHAN field of a ps -alx listing.

Never trust an operating system you don't have sources for. ;-)
