We've distilled this into a reproducible environment with a stack of NFS + XFS to a local disk + automated sysrq 'b' reboots. We're working on getting this bundled up into a nice little package as a VirtualBox vm for your consumption. Please tell me if this is not desirable.
The self-contained and reproducible environment can be downloaded from the following location:

Has anyone by chance had an opportunity to utilize this?  Any corruption 
reports?

Looked at it, but it turns virtualbox is a real big pile of junk
including it's own huge kernel module.  Qemu/kvm now has support for the
virtualbox disk images and I will give it a try next.

Ping ... sorry to be a bother. I've finally gotten some time allocated to look at this at the code level, but I'm unfamiliar with the XFS implementation, and I believe this problem arises as an interaction between XFS and NFS, which causes me heartburn. I'll report here if I discover anything meaningful.
