Hi Brain,
Sorry for the wrong file in previous message. I believe this the right one.
https://cloud.swiftstack.com/v1/AUTH_hugo/public/xfs.ko.debug
/usr/lib/debug/lib/modules/2.6.32-504.23.4.el6.x86_64/kernel/fs/xfs/xfs.ko.debug
MD5 : 27829c9c55f4f5b095d29a7de7c27254
Thanks // Hugo

No, this isn't the debug version. We need the one from the debug package
