I have went back to the .90 kernel and tried my same test (ie dd
if=floppy of=/dev/fd0) and no errors came up in syslog. What has
changed that could possibly cause this sort of thing? lance.c had not
changed, but floppy.c has. I don't know too much about the internals of
the kernel, and I would hate to do a bunch of work for nothing. Do you
have any suggestions for starting points or other ideas? (It seems a
little odd that floppy.c alone could cause bus errors)

Thanks,

(BTW I read this list from news.fuller.edu and neither of these replies
have shown up there yet. Either it is real slow, or there is a problem.
Basically, don't count on me seeing anything that isn't mailed directly
to me.)
