I would suggest to report your issue based on current observations rather than rely on it looking similar to an old report. See the following for what information is relevant to include when reporting a problem: http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F Note that the syslog and hung task output is particularly relevant here.
