Could you explain what the issue actually is?
Normally even trying to ls a directory containing eg a link to a missing
NFS directory hangs.
Are you saying that doing dired on a local directory that contains a
link to a missing NFS mount works, but hangs in calling df to calculate
the 'total used xxx available yyy' part?
What does ls-lisp have to do with it?
I can see how adding -l might help with a plain `df' call, but how can
it help `df DIR' if DIR is local?
