xfs_logprint doesn't find any problems with this log but that doesn't mean the kernel doesn't - they use different implementations to read the log. I noticed that the active part of the log wraps around the physical end/start of the log which reminds of this fix:
Very interesting indeed, thank you /very/ much for looking at this.
I think the fix made it into 2.6.24.
We're currently using the very latest 2.6.30, unfortunately. 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. Thanks very much again. John Quigley jquigley.com
