No problem. When I booted to 2.6.16 and ran xfs_repair on my
benchmark XFS partition, it fixed some sort of corruption and
I was able to delete the empty directories. I find it curious
that it only happens on SATA drives, so I'll be interested to
see what the problem and solution ends up being. 

If it matters, the SATA drive in question uses the sata_sil
driver.

Indeed I did. The test finished up over night without incident.

Kurt
