Hi, I was running a dpdk application with e1000 driver and I am facing a rare driver lockup condition. Under this condition, what I am seeing is that the Receive side locks up. The transmit side is fine. When I execute "rte_eth_dev_stop()/rte_eth_dev_start()" from within the VM, the dpdk application recovers. The lockup happens once in 2 or 3 days if I continuously ping an IP address serviced by the dpdk application. Once it locks up, what I am noticing is that even though packets are coming in, the driver is not populating them and signaling the event. In other words, in "eth_em_recv_pkts" call, I am not seeing "E1000_RXD_STAT_DD" being set for status, and the driver bails out. If anyone has come across such condition, please let me know? Appreciate the help.
Environment: I have a VM running on top of Ubuntu/KVM. Application: Running dpdk-2.0.0. VM: uses e1000 driver. On the KVM side, our port is sitting in a bridge. There are other VNFs that we use for testing and some of them are using virtio driver. Thank You regards Prab
