kernel crash with damaged XFS

[Michael Monnerie]

I had that during the last days on my system. It kept on running despite
this error. I xfs_repair'ed the fs again and now it's working.
This is the same server I talked about with Eric last time, where he
improved xfs_repair and that repaired my fs. I had to run
xfs_repair several times again until all errors were solved,
and now nothing is reported anymore.
The server had no crash or whatever since the last repair, so I wonder
where these corruptions come from.
