Did you ever run 2.6.17-2.6.17.6? If so, this implies:

Yes, but those previous corruptions get left on disk as a landmine
for you to trip over some time later, even on a kernel that has the
bug fixed.
I suggest that you run xfs_check on the filesystem and if that
shows up errors, run xfs_repair onteh filesystem to correct them.
