I don't want to cause work for anyone.  Let me run a surface scan of
the disk with analyze and see if the disk is shot.  If all is well
then I will restore from ufsdumps and see what fsck says again.  If we
still get complaints then perhaps there is a problem.

This is on UltraSparc by the way although I expect the code to be the
same regardless.
