	I have been hit with this bug as well - I tried to clear the
two corrupted directory inodes with xfs_db (as the FAQ entry says), then ran
xfs_repair (lots of files ended up in lost+found), but apparently
the volume is still not OK - when I tried to use it (this volume
is a public FTP archive), I got the following traces:

	This is 2.6.17.7 dual x86_64 (Fedora Core 5). It has been unfortunately
running 2.6.17.1 for some time.

	I will probably have to recreate the volume and restore its
contents from backups. Or is there any better solution?

	Thanks,
