>Description:

i recently tried to newfs a filesystem on a floppy.  i wasn't greeted
with anything...nice  :-)

here's a console log of the events that took place.  i do have the crash
dumps still (2 of them, i can easily generate more).  i can reproduce
this by trying to access _any_ fd device.

if you look closely, you'll see it's trying to print this:

fd0: timeout

but, it gets an interupt for each character it prints, after the first
3.  it's _always_ this same sequence.

if you require more info, just ask.  i'm wanting to get this working
fairly soon (for the 1.1 release -- boot floppies for the sparc! :-)
