While running xfstests on an NFS/RDMA mount, I see this in the client's /var/log/messages multiple times: Jun 22 14:13:45 manet kernel: mlx5_0:dump_cqe:275:(pid 0): dump error cqe Jun 22 14:13:45 manet kernel: 00000000 00000000 00000000 00000000 Jun 22 14:13:45 manet kernel: 00000000 00000000 00000000 00000000 Jun 22 14:13:45 manet kernel: 00000000 00000000 00000000 00000000 Jun 22 14:13:45 manet kernel: 00000000 08007806 250000cd 024027d3 Jun 22 14:13:45 manet kernel: rpcrdma: fastreg: memory management operation error (6/0x78) As far as I can tell the client is able to recover and continue the test. However, this error is not supposed to happen in normal operation. This is with a Mellanox CX4 in RoCEv1 mode, v4.12-rc2. -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
