Are you using a 2.6 kernel?  Then the workaround is not to use
xfs_freeze when creating snapshots!  No device-mapper-based snapshots
have ever needed it.  Why do people persist in thinking incorrectly that
XFS is the only filesystem that has to be told explicitly to do this?

Device-mapper snapshots in *all* kernels provide this functionality
automatically provided the filesystem supports it, which XFS does.
