If you are using the kernel exporting then killing the daemon with -9 might
not be immediately cleaning up since some state is in the kernel and some in
the process. If that is happening then it might be taking a while for the
kernel to detect the problem and clean up.
Since the fs is busy while it is exported, you can't unmount it.
If you do this cleanly with exportfs -u ... then you should be able to unmount
yaffs.
