State-Changed-Why: 
It seems that the code path referenced invalid address when a mbuf
length is odd bytes.  I created a new diff based on your patch
since your patch may still invoke bus_space_write_1(9) if mbuf
length is even bytes.  I also added mbuf length check and used NULL
in comparing a mbuf pointer.

You can find the patch at the following URL.

Let me know whether this patch works for you.
