AMD64, FreeBSD 10.0-STABLE #4 r270560: This is on an Intel MB S1200BTL ( S1200BT.86B.02.00.0035.030220120927) Unfortunately, this is also a production box so its difficult to test. I am going to see if I can find a similar MB to test against. # pciconf -lvcb em1 em1@pci0:2:0:0: class=0x020000 card=0x35788086 chip=0x10d38086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = '82574L Gigabit Network Connection' class = network subclass = ethernet bar [10] = type Memory, range 32, base 0xc2300000, size 131072, enabled bar [18] = type I/O Port, range 32, base 0x2000, size 32, enabled bar [1c] = type Memory, range 32, base 0xc2320000, size 16384, enabled 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) speed 2.5(2.5) ASPM disabled(L0s/L1) cap 11[a0] = MSI-X supports 5 messages Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] ecap 0001[100] = AER 1 0 fatal 0 non-fatal 0 corrected ecap 0003[140] = Serial 1 001e67ffff4931b8 Sep 12 09:31:17 hast-a kernel: em1: Watchdog timeout -- resetting Sep 12 09:31:17 hast-a kernel: em1: Queue(0) tdh = 174, hw tdt = 128 Sep 12 09:31:17 hast-a kernel: em1: TX(0) desc avail = 31,Next TX to Clean = 159 Sep 12 09:31:17 hast-a kernel: em1: link state changed to DOWN Sep 12 09:31:17 hast-a kernel: vlan5: link state changed to DOWN Sep 12 09:31:20 hast-a kernel: em1: link state changed to UP Sep 12 09:31:20 hast-a kernel: vlan5: link state changed to UP dev.em.1.%desc: Intel(R) PRO/1000 Network Connection 7.4.2 dev.em.1.%driver: em dev.em.1.%location: slot=0 function=0 handle=\_SB_.PCI0.RP05.GBE2 dev.em.1.%pnpinfo: vendor=0x8086 device=0x10d3 subvendor=0x8086 subdevice=0x3578 class=0x020000 dev.em.1.%parent: pci2 dev.em.1.nvm: -1 dev.em.1.debug: -1 dev.em.1.fc: 3 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.itr: 488 dev.em.1.rx_processing_limit: 100 dev.em.1.eee_control: 1 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.rx_overruns: 0 dev.em.1.watchdog_timeouts: 2 dev.em.1.device_control: 1074790984 dev.em.1.rx_control: 67141634 dev.em.1.fc_high_water: 18432 dev.em.1.fc_low_water: 16932 dev.em.1.queue0.txd_head: 35 dev.em.1.queue0.txd_tail: 35 dev.em.1.queue0.tx_irq: 0 dev.em.1.queue0.no_desc_avail: 6 dev.em.1.queue0.rxd_head: 4 dev.em.1.queue0.rxd_tail: 3 dev.em.1.queue0.rx_irq: 0 dev.em.1.mac_stats.excess_coll: 0 dev.em.1.mac_stats.single_coll: 0 dev.em.1.mac_stats.multiple_coll: 0 dev.em.1.mac_stats.late_coll: 0 dev.em.1.mac_stats.collision_count: 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: 0 dev.em.1.mac_stats.recv_no_buff: 0 dev.em.1.mac_stats.recv_undersize: 0 dev.em.1.mac_stats.recv_fragmented: 0 dev.em.1.mac_stats.recv_oversize: 0 dev.em.1.mac_stats.recv_jabber: 0 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.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: 1695862162 dev.em.1.mac_stats.good_pkts_recvd: 1695862162 dev.em.1.mac_stats.bcast_pkts_recvd: 235092 dev.em.1.mac_stats.mcast_pkts_recvd: 11373 dev.em.1.mac_stats.rx_frames_64: 167700 dev.em.1.mac_stats.rx_frames_65_127: 1640908832 dev.em.1.mac_stats.rx_frames_128_255: 53712726 dev.em.1.mac_stats.rx_frames_256_511: 26150 dev.em.1.mac_stats.rx_frames_512_1023: 69118 dev.em.1.mac_stats.rx_frames_1024_1522: 977636 dev.em.1.mac_stats.good_octets_recvd: 131684743469 dev.em.1.mac_stats.good_octets_txd: 4643270636718 dev.em.1.mac_stats.total_pkts_txd: 3220545297 dev.em.1.mac_stats.good_pkts_txd: 3220545297 dev.em.1.mac_stats.bcast_pkts_txd: 2038 dev.em.1.mac_stats.mcast_pkts_txd: 2 dev.em.1.mac_stats.tx_frames_64: 2192 dev.em.1.mac_stats.tx_frames_65_127: 57674879 dev.em.1.mac_stats.tx_frames_128_255: 66706189 dev.em.1.mac_stats.tx_frames_256_511: 4031061 dev.em.1.mac_stats.tx_frames_512_1023: 136967178 dev.em.1.mac_stats.tx_frames_1024_1522: 2955163798 dev.em.1.mac_stats.tso_txd: 250622342 dev.em.1.mac_stats.tso_ctx_fail: 0 dev.em.1.interrupts.asserts: 420159909 dev.em.1.interrupts.rx_pkt_timer: 193315 dev.em.1.interrupts.rx_abs_timer: 0 dev.em.1.interrupts.tx_pkt_timer: 9886 dev.em.1.interrupts.tx_abs_timer: 15943 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.wake: 0 -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
