I'm not the person above that said to "try to avoid", but I do have some 
info regarding this.

It isn't that they won't work, just you *may* have issues with 4k 
stacks.  Here is one of the reasons: http://lkml.org/lkml/2004/7/20/62 
.  Basically there is a potential for a kernel oops if the XFS 
filesystem gets *near* full and tries to free some reserved space.  
There was another reason posted on the lkml, but I don't recall it nor 
have a link handy (sorry).

That being said.  XFS has been working great for me and I have no 
intention of changing in the near term.  Of course I still use 8K stacks 
though (on 2.6.9-rc2).
