This is the level of service and complexity where, really, you want
access to the people who wrote the kernel. That can mean buying some
licenses and submitting the bugs directly to the upstream vendor,
becuase that loolks like fairly deep kernel issues.

Also, *why* are you mixing xfs and nfs services in the same
envirnment? And what kind of NFS and XFS servers are you using?
