Well, there was that one time a while back (late November?) where
XFS was broken (clean shutdown would prevent a boot due to some
block information being confused)  I reverted and recovered back then
and had not had a crash (unclean shutdown) since then.

Also, some more information:  xfs_check was returning that the system
was clean (all OK, not even a minor warning) and yet I had a number of
"mtab" files in /etc.  In fact, I had a hard time getting rid of them.
Using "rm" did not work well (that would really confuse the directory
and required a shutdown/reboot to recover from - and still multiple
/etc/mtab files)

In finally fixed it my doing a "mv /etc/mtab* /junk/" (I had created
that directory.  All of the mtab file entries were no gone from /etc
and /junk had only one.  (and a simple rm -rf /junk cleaned that up)

xfs_check still claims all is fine.
