Were you able to investigate the traces? Breaking NFS mounts from Qnap (knfsd with 3.4.6 kernel here, though Qnap might have patched it),is not something that should happen with a -stable kernel update, even if the problem would be on the Qnap side, which would not be completely surprising. So I think we should revert this patch at least for -stable, unless we understand what's going on and have a better fix than a plain revert. Best, -- Kurt Garloff
