This is xfsprogs 2.6.20-1 from debian/sarge. SGI has 2.6.25 I will try that,
and report back.

This is definetly not a badblock problem, consider this setup:

/dev/rootvg/dom2xfslv in domain0 gets exported to the domain "dom2" as hda2.

creating and checking xfs/reiserfs filesystems in domain0 on
/dev/rootvg/dom2xfslv works fine

creating and checking xfs/reiserfs filesystems in dom2 on
/dev/hda2 fails.

The disk blocks under domain0:/dev/rootvg/dom2xfslv and dom2:/dev/hda2 are
the same. mkfs/fsck versions are the same in both domains.
