Hi,
I second Patrick McLean's e-mail from 2007/02/27.
Patrick also said he was using nfsd at that point.

=======================
Running Slackware 2.6.24.3-smp stock kernel. However, ntpdate ran 1
minute before this occurred (offset 7.4 seconds). Machine was running
rsync to a remote NFS server (common rsync, not using rsync protocol)
mounted at the local machine.

I have this message in the dmesg on a mail server running on an xfs
filesystem. It appears to have happened at some point when nfsd was
restarted, but I can't seem to convince it to reproduce.
The machine is running Gentoo's 2.6.20 kernel.

Here, the check itself has been racy (and producing bogus warnings) and
is already removed in current Linus's tree. Thanks for report.
