xfsrestore fails to exit properly under 2.6.1

[Phil Macias <Philip.Macias@xxxxxxxx>]

Hello,

We have been using XFS on RedHat linux for over two years (since I
have been here). I have been using a script to clone workstations from
one-another for over a year whereby the host-to-be-cloned exports it's
XFS partitions over NFS and they are mounted by the donor host and
contents copied with:

      xfsdump -v5 -l 0 - /dev/hda7 | xfsrestore -v5 - /clone-var

This process worked reliably for over a year on the 2.4.x kernels and
these versions of xfs tools:

  acl-2.1.1-gfdl-1-1
  attr-2.1.1-gfdl-1-1
  dmapi-2.0.5-gfdl-1-1
  kernel-2.4.18-XFS-NFS-base-gfdl-2-1
  xfsdump-2.2.4-gfdl-1-1
  xfsprogs-2.3.6-gfdl-1-1

PROBLEM: I am testing the 2.6.1 kernel and the following relevant
packages: 

  libelf-0.8.2-2-gfdl-1-1
  elfutils-libelf-0.89-2-gfdl-1-1
  popt-1.8.1-0.31-gfdl-1-1
  gcc-3.3-gfdl-1-1
  kernel-2.6.0-complete-gfdl-1-1
  glibc-2.3.2-gfdl-1-1
  beecrypt-3.0.1-gfdl-1-1
  
  acl-2.2.21-gfdl.tgz
  attr-2.4.12-gfdl.tgz
  binutils-2.14-gfdl.tgz
  dmapi-2.1.0-gfdl.tgz
  xfsprogs-2.6.0-gfdl.tgz
           
Everything on the system works well except the remote
xfsdump/xfsrestore. Running:

      xfsdump -v5 -l 0 - /dev/hda7 | xfsrestore -v5 - /clone-var

on the 2.6.1 system does dump/restore properly, but xfsrestore never
exits. I have to issue these commands to release xfsrestore:

  kill %
  fuser -k /clone-var/

        ...where /clone-var/ is the target partition. Please note that
        the target host is still running the old (2.4.x) kernel.

Here are the last lines to the "-v5" output:

  -------------------------------------------------

Syslog shows no erors or any info about xfsrestore.

Any idea why xfsrestore fails to exit properly?

Thanx,
