We eventually found that even after we thought it was "mostly working" it 
really wasn't.  Only the failure mode had changed from "Stale
NFS file handle" and an inability to access below the mounted directory to 
full directory traversal, but i/o errors when trying to read files.  We 
ended up having to downgrade to an older kernel.

I did a cvs recheckout, and I see there have been xfs changes in 2.4 in 
the past two months, but I'm very hesitant to try again unless its known 
that XFS+NFS was broken in CVS 2-3 months ago and is believed to be fixed 
now.  Had anyone else run into this?
