That's it.  What does

x/s 0xc09811a1

show?  It will be the format string for the panic message, which I'm
guessing is your

       KASSERT(!(bp->b_vflags & BV_BKGRDINPROG),
            ("FFS background buffer should not get here %p", bp));

again.  Anyway, dump core if you can in case phk needs to see it.
