Hi Olga, any updates? 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 <kurt@xxxxxxxxxx>
