Debian Etch, 2.6.13.4, stopped working a while ago, either before newer
debian packages or a newer kernel, does anyone who uses Debian+XFS have
this problem as well?

Is this a kernel, XFS or Debian problem?
Thanks!

I see it too - this looks like an endian issue in xfs_db, this patch
should fix it (Works For Me).
