XFS: the filesystem of the future?

Do you have any other details on this? I have a sneaking suspicion this is EXACTLY what I was seeing on a little VIA box of mine that I blamed on a faulty I/O daughterboard.

I was using a 1/2 TB external USB drive with XFS for my MythTV recordings, shared over the LAN via NFSv4... and I saw hard lockups every few weeks, pretty reliably.
