I join info in attached files.
Chronology:
Problem detected on FS.
FS unmounted
multiple xfs_repair -P with message in my precedent mail
A try to remount FS give a kernel panic
FS is unmounted actually.
Metadump compressed file is 1,4 Gb

What kernel/xfsprogs version, xfs_info, mount options? Do you have the
full xfs_repair output? In general:
http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F
It's not clear to me from your report whether repair fixed this or
failed itself. Also, can you compress the metadump image?
