These above stack trace is the sign of a corrupted directory.

Where we saw signs of on disk directory corruption. Have you run
xfs_repair successfully on the filesystem since you reported
this?
If you did clean up the error, does xfs_repair report the same sort
of error again?
Have you run a 2.6.16-rcX or 2.6.17.[0-6] kernel since you last
reported this problem?
Cheers,
Dave.
