The HCA is Mellanox Technologies MT26428.
Reproduction:
1) Mount a directory via NFS/RDMA
mount -t nfs -o port=20049,rdma,vers=4.0,timeo=900 172.16.100.2:/ /mnt/
2) Pull the Infiniband cable or use ibportstate to disrupt the Infiniband connection
3) ls /mnt
4) wait 5-30 seconds

My first post was misleading -- I use the vanilla 3.10.17 kernel, and the error occurs with and without Mellanox OFED. The above report
references the vanilla kernel.
