On the iostat screen of systat, fd0 is shown to be active when sd0 is active. sd0 is legitmately active, but most of the time fd0 isn't. I am assuming that fd0 is the floppy disk. How-To-Repeat: start up systat, type :iostat. watch, see if it makes sense.
State Changed From-To: open->closed Problem was caused by now-fixed bug in ncr driver.
