Include as much information as you can about the filesystem, storage and
problem:
http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F
For a repair crash, the full output of the repair is a good start. Also, an
xfs_metadump of the fs is probably the most effective tool to help us try and
reproduce the problem, if you have somewhere you can post one.
