Hundreds of these messages in ovs-vswitchd.log: 2023-08-11T23:02:07.634Z|00017|dpdk|WARN|ice_interrupt_handler(): OICR: MDD event Version-Release number of selected component (if applicable): RHEL-9.2.0-updates-20230809.16 kernel version: 5.14.0-284.27.1.el9_2.x86_64 [root@netqe44 openvswitch]# rpm -qa | grep openvswitch openvswitch-selinux-extra-policy-1.0-34.el9fdp.noarch openvswitch3.2-3.2.0-0.2.el9fdp.x86_64 python3-openvswitch3.2-3.2.0-0.2.el9fdp.x86_64 openvswitch3.2-test-3.2.0-0.2.el9fdp.noarch How reproducible: Steps to Reproduce: 1. Observed in automated topology tests 2. 3. Actual results: VMs cannot ping each other nor send traffic. Expected results: VMs can successfully ping each other and send traffic. Additional info: Problem only happens with the tests referenced below and only in ovs-dpdk environment: ovs_test_vm_nic ovs_test_vm_multiple_vlans ovs_test_vm_vlan_id0 ovs_test_vm_gre1_ipv6 ovs_test_vm_gre_flow_ipv6 ovs_test_vm_vlan_gre1_ipv6 ovs_test_vlan_mode_access_vm ovs_test_vlan_mode_trunk_vm ovs_test_vlan_mode_native_untagged_vm ovs_test_vlan_mode_native_tagged_vm - Same tests run with same versions against Mellanox ConnectX6 DX card (mlx5_core) show no problem. - Same tests run against E810 ice card pass 100% using openvswitch3.1 from FDP 23.F with RHEL-9.2. - This issue is also seen on these same tests using openvswitch3.2 with RHEL-9.3. Note: VMs are running RHEL-8.6 instead of RHEL-9.2 due to BZ https://bugzilla.redhat.com/show_bug.cgi?id=2184976 but problem is also seen using RHEL-9.2 VM with RHEL-9.3 which contains the fix for https://bugzilla.redhat.com/show_bug.cgi?id=2184976. sos reports can be found here: http://netqe-infra01.knqe.lab.eng.bos.redhat.com/sosreports/sosreport-netqe31-2023-08-12-ejsinsu.tar.xz http://netqe-infra01.knqe.lab.eng.bos.redhat.com/sosreports/sosreport-netqe44-2023-08-12-pxttxtk.tar.xz Beaker job links: openvswitch3.2, RHEL-9.2: https://beaker.engineering.redhat.com/jobs/8180530 openvswitch3.2, RHEL-9.3: https://beaker.engineering.redhat.com/jobs/8182138 openvswitch3.1, RHEL-9.2: https://beaker.engineering.redhat.com/jobs/8089673
