I have had some problems with XFS on a Debian-based AFS fileserver.  XFS 
decided to off-line a volume due to a long timeout in the underlying 
RAID volume.  I would not recomend it without heavy testing.

I'll note that someone mentioned a problem with the 8192 stack size in 
Debian a few months ago in the #openafs IRC channel.  They worked around 
the problem with via changing some setting before starting the AFS 
processes.  Unfortunately I do not remember the exact solution or the 
exact problem, but you are not the only one experiencing it.
