Why trying to do a dump I am getting a series of

dscheck(#da/36): negative b_blkno -1534422967
dscheck(#da/36): negative b_blkno -1534422966
dscheck(#da/36): negative b_blkno -1534422965
dscheck(#da/36): negative b_blkno -1534422964


logged in kern.* as a result of dump trying to do something.  I dont get 
the errors when reading any of the files, only when using dump.

What does this mean ?  fsck does not seem to find anything wrong.
