Just for the record, I just encountered the same error, with the *same block
number*:
corbeau:~# xfs_repair /dev/sda3
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...

- agno = 14
- agno = 15
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- clear lost+found (if it exists) ...
- clearing existing "lost+found" inode
- deleting existing "lost+found" entry
- check for inodes claiming duplicate blocks...

Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- ensuring existence of lost+found directory

This is a 2.6.15.7 kernel, with xfs_repair 2.6.20, on Debian Sarge.
The filesystem is on top of a SATA drive:
