Hi, Both of my servers are running with kernel 4.14.178 and have Intel Ethernet Network Adapter X722. Also the IOMMU is disabled. I was trying to run qperf and ran into couple of issues: 1) While running any bw test, eg. rc_bw or rc_bi_bw, I see following messages in dmesg: i40iw_cqp_ce_handler: opcode = 0x1 maj_err_code = 0xffff min_err_code = 0x8007 i40iw_wait_event: error cqp command 0xb completion maj = 0xffff min=0x8007 2) Following rc benchmarks fail: rc_rdma_write_bw, rc_rdma_write_lat, rc_compare_swap_mr, rc_fetch_add_mr, ver_rc_compare_swap and ver_rc_fetch_add. For these I get error of failed to post "benchmark name" Am I missing something here? Any suggestions? Thanks, Anubhav
