A quick glance at the source code seems to indicate that there was an
actual CRC error (on disk) at this point, so that could be a RAID
problem;

OTOH it looks really similar to an older bug :

http://oss.sgi.com/archives/xfs/2013-02/msg00482.html

AFAIK this one could be related to the current Ubuntu LTS lvm stack...
We need Dave's advice on this one.

Was there nothing in the xfs_repair output? nothing in lost+found
either?
