OK, so in the meantime I found a bug in data=journal code which could be related to your problem. It is fixed by commit 2d859db3e4a82a365572592d57624a5f996ed0ec which is in 3.1-rc1. Have you tried that or newer kernel as well? If the problem still is not fixed, I can provide some debugging patch to you. We spoke with Josef Bacik how errors like yours could happen so I have some places to watch...
