I can confirm that v3.13.9 does in fact exhibit the bug. I installed linux-image-3.13.9-031309-generic_3.13.9-031309.201404031554_amd64.deb and rebooted into the new kernel. Running uname -r shows "3.13.9-031309-generic". Mounting an nfs share, even when shared from localhost, results in a long delay of 16 seconds or more.
