First off,
http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F
But for starters, which kernel are you running, what did the kernel say when mount failed, what is the storage beneath the filesystem, what sort of caching does it have, and what is the status of the barrier mount option for this filesystem?
