If igb_alloc_rx_queue_mbufs() would fail to allocate an mbuf for RX queue, it calls igb_rx_queue_release(rxq). That causes rxq to be silently freed, without updating dev->data->rx_queues[]. So any further reference to it will trigger the SIGSEGV. Same thing in em PMD too. To fix: igb_alloc_rx_queue_mbufs() should just return an error to the caller and let upper layer to deal with the probem. That's what ixgbe PMD is doing right now.
