I'm puzzled that you've had NFS stable enough to test these. How much testing has this stuff had? Here 2.5.60+bk clients fall over under moderate NFS load. (And go splat quickly under high load).
Trying to run things like dbench causes lockups, fsx/fstress made it reboot, plus the odd 'cheating' errors reported yesterday.
