Can you report your HCA and how you reproduce this issue? 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 > > Do you (or does anyone) know whether OpenSuSE uses the stock upstream providers, or has any of OFED been applied to this kernel? 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. Rafael
