Looking at the data, it seems that the .. entry in the directory does
not match the fid of the entry for the parent.

So, it seems that
 dir 0x47 has an entry for
   dir in 0x449 has an entry for
     dir in 0x451

So the dir in 0x451 has a bad parent pointer.

Any clues on how to fix this?

1) I am tempted to comment out the ASSERT (or add to skipsalvage),
move all the stuff from the problem dir, and then rmdir it.

2) use norton to delete the .. entry in the vnode and recreate it.

So I tried 2 and 

norton> delete name 0x1000002 0x451 0x4d46 .. 1
norton> create name 0x1000002 0x451 0x4d46  .. 0x449 0x4d42

08:45:29 JE: parent = 0x1000002.47.380a ; child thinks parent is 0x451.4d46; Shouldnt Happen

So I'm not sure if something else bad happened.  I'll keep poking.
I'm partially posting because I think this indicates some sort of
server bug.  It would be cool if the salvage could fix these
backpointers a la fsck.
