Very interesting indeed, thank you /very/ much for looking at this.

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.
