Thanks, looking forward to trying it out! With respect to the multiple queues, I thought the driver already used just the one on RELENG_8 ? If not, is there a way to force the existing driver to use just the one queue ? On the box that has the NIC locking up, it shows em1@pci0:9:0:0: class=0x020000 card=0x34ec8086 chip=0x10d38086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = 'Intel 82574L Gigabit Ethernet Controller (82574L)' class = network subclass = ethernet cap 01[c8] = powerspec 2 supports D0 D3 current D0 cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message cap 10[e0] = PCI-Express 1 endpoint max data 128(256) link x1(x1) and vmstat -i shows irq256: em0 5129063 353 irq257: em1 531251 36 in a wedged state, stats look like dev.em.1.%desc: Intel(R) PRO/1000 Network Connection 7.0.5 dev.em.1.%driver: em dev.em.1.%location: slot=0 function=0 handle=\_SB_.PCI0.PEX4.HART dev.em.1.%pnpinfo: vendor=0x8086 device=0x10d3 subvendor=0x8086 subdevice=0x34ec class=0x020000 dev.em.1.%parent: pci9 dev.em.1.nvm: -1 dev.em.1.rx_int_delay: 0 dev.em.1.tx_int_delay: 66 dev.em.1.rx_abs_int_delay: 66 dev.em.1.tx_abs_int_delay: 66 dev.em.1.rx_processing_limit: 100 dev.em.1.link_irq: 0 dev.em.1.mbuf_alloc_fail: 0 dev.em.1.cluster_alloc_fail: 0 dev.em.1.dropped: 0 dev.em.1.tx_dma_fail: 0 dev.em.1.fc_high_water: 18432 dev.em.1.fc_low_water: 16932 dev.em.1.mac_stats.excess_coll: 0 dev.em.1.mac_stats.symbol_errors: 0 dev.em.1.mac_stats.sequence_errors: 0 dev.em.1.mac_stats.defer_count: 0 dev.em.1.mac_stats.missed_packets: 41522 dev.em.1.mac_stats.recv_no_buff: 19 dev.em.1.mac_stats.recv_errs: 0 dev.em.1.mac_stats.crc_errs: 0 dev.em.1.mac_stats.alignment_errs: 0 dev.em.1.mac_stats.coll_ext_errs: 0 dev.em.1.mac_stats.rx_overruns: 41398 dev.em.1.mac_stats.watchdog_timeouts: 0 dev.em.1.mac_stats.xon_recvd: 0 dev.em.1.mac_stats.xon_txd: 0 dev.em.1.mac_stats.xoff_recvd: 0 dev.em.1.mac_stats.xoff_txd: 0 dev.em.1.mac_stats.total_pkts_recvd: 95229129 dev.em.1.mac_stats.good_pkts_recvd: 95187607 dev.em.1.mac_stats.bcast_pkts_recvd: 79244 dev.em.1.mac_stats.mcast_pkts_recvd: 0 dev.em.1.mac_stats.rx_frames_64: 93680 dev.em.1.mac_stats.rx_frames_65_127: 1516349 dev.em.1.mac_stats.rx_frames_128_255: 4464941 dev.em.1.mac_stats.rx_frames_256_511: 4024 dev.em.1.mac_stats.rx_frames_512_1023: 2096067 dev.em.1.mac_stats.rx_frames_1024_1522: 87012546 dev.em.1.mac_stats.good_octets_recvd: 0 dev.em.1.mac_stats.good_octest_txd: 0 dev.em.1.mac_stats.total_pkts_txd: 66775098 dev.em.1.mac_stats.good_pkts_txd: 66775098 dev.em.1.mac_stats.bcast_pkts_txd: 509 dev.em.1.mac_stats.mcast_pkts_txd: 7 dev.em.1.mac_stats.tx_frames_64: 48038472 dev.em.1.mac_stats.tx_frames_65_127: 13402833 dev.em.1.mac_stats.tx_frames_128_255: 5324413 dev.em.1.mac_stats.tx_frames_256_511: 957 dev.em.1.mac_stats.tx_frames_512_1023: 319 dev.em.1.mac_stats.tx_frames_1024_1522: 8104 dev.em.1.mac_stats.tso_txd: 1069 dev.em.1.mac_stats.tso_ctx_fail: 0 dev.em.1.interrupts.asserts: 0 dev.em.1.interrupts.rx_pkt_timer: 0 dev.em.1.interrupts.rx_abs_timer: 0 dev.em.1.interrupts.tx_pkt_timer: 0 dev.em.1.interrupts.tx_abs_timer: 0 dev.em.1.interrupts.tx_queue_empty: 0 dev.em.1.interrupts.tx_queue_min_thresh: 0 dev.em.1.interrupts.rx_desc_min_thresh: 0 dev.em.1.interrupts.rx_overrun: 0 dev.em.1.host.breaker_tx_pkt: 0 dev.em.1.host.host_tx_pkt_discard: 0 dev.em.1.host.rx_pkt: 0 dev.em.1.host.breaker_rx_pkts: 0 dev.em.1.host.breaker_rx_pkt_drop: 0 dev.em.1.host.tx_good_pkt: 0 dev.em.1.host.breaker_tx_pkt_drop: 0 dev.em.1.host.rx_good_bytes: 0 dev.em.1.host.tx_good_bytes: 0 dev.em.1.host.length_errors: 0 dev.em.1.host.serdes_violation_pkt: 0 dev.em.1.host.header_redir_missed: 0 ifconfig down/up just panics or locks up the box when its in this state.
