It seems I just hadn't used a recent enough xfs_repair with that 
filesystem. Seems good now. Just one last question, are you 99,5% sure 
that this is the symptoms of that corruption bug in 2.6.17? So I can 
assume that my memory wasn't the problem? I'm now running with only 
512MB (which I'm sure is good), and I don't want to use the new memory 
if I get this problem again (even though I have good backups, it's a 
hell of a job fixing it again...)

Thank you.

Best regards,
