Using autoselect, the interface defaults to 100baseTX, and setting it to 1000baseT or 1000baseTX either half- or full-duplex simply disconnects the controller from the network and changes its status to "no carrier". Changing the media to 100baseTX or autoselect again brings back the connection. I have tried replacing the cable and connecting the machine to several different (gigabit) devices, but nothing helps. dmesg does not output anything out of the ordinary. The other network interface in the machine, an onboard Realtek, does not have any problems and autonegotiates to gigabit just fine. The system is an Intel D945GCLF2D dual-core Atom 330 running FreeBSD/amd64. lspci: 04:00.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) dmesg: em0: <Intel(R) PRO/1000 Legacy Network Connection 1.0.4> port 0x1000-0x103f mem 0x88120000-0x8813ffff,0x88100000-0x8811ffff irq 21 at device 0.0 on pci4 sysctl dev.em: dev.em.0.%desc: Intel(R) PRO/1000 Legacy Network Connection 1.0.4 dev.em.0.%driver: em dev.em.0.%location: slot=0 function=0 dev.em.0.%pnpinfo: vendor=0x8086 device=0x107c subvendor=0x8086 subdevice=0x1376 class=0x020000 dev.em.0.%parent: pci4 dev.em.0.nvm: -1 dev.em.0.rx_int_delay: 0 dev.em.0.tx_int_delay: 66 dev.em.0.rx_abs_int_delay: 66 dev.em.0.tx_abs_int_delay: 66 dev.em.0.rx_processing_limit: 100 dev.em.0.flow_control: 3 dev.em.0.mbuf_alloc_fail: 0 dev.em.0.cluster_alloc_fail: 0 dev.em.0.dropped: 0 dev.em.0.tx_dma_fail: 0 dev.em.0.tx_desc_fail1: 0 dev.em.0.tx_desc_fail2: 145326 dev.em.0.rx_overruns: 0 dev.em.0.watchdog_timeouts: 0 dev.em.0.device_control: 1480327745 dev.em.0.rx_control: 32770 dev.em.0.fc_high_water: 47104 dev.em.0.fc_low_water: 45604 dev.em.0.fifo_workaround: 0 dev.em.0.fifo_reset: 0 dev.em.0.txd_head: 243 dev.em.0.txd_tail: 243 dev.em.0.rxd_head: 14 dev.em.0.rxd_tail: 12 dev.em.0.mac_stats.excess_coll: 0 dev.em.0.mac_stats.single_coll: 0 dev.em.0.mac_stats.multiple_coll: 0 dev.em.0.mac_stats.late_coll: 0 dev.em.0.mac_stats.collision_count: 0 dev.em.0.mac_stats.symbol_errors: 0 dev.em.0.mac_stats.sequence_errors: 0 dev.em.0.mac_stats.defer_count: 0 dev.em.0.mac_stats.missed_packets: 0 dev.em.0.mac_stats.recv_no_buff: 0 dev.em.0.mac_stats.recv_undersize: 0 dev.em.0.mac_stats.recv_fragmented: 0 dev.em.0.mac_stats.recv_oversize: 0 dev.em.0.mac_stats.recv_jabber: 0 dev.em.0.mac_stats.recv_errs: 0 dev.em.0.mac_stats.crc_errs: 0 dev.em.0.mac_stats.alignment_errs: 0 dev.em.0.mac_stats.coll_ext_errs: 0 dev.em.0.mac_stats.xon_recvd: 0 dev.em.0.mac_stats.xon_txd: 0 dev.em.0.mac_stats.xoff_recvd: 0 dev.em.0.mac_stats.xoff_txd: 0 dev.em.0.mac_stats.total_pkts_recvd: 27700266 dev.em.0.mac_stats.good_pkts_recvd: 27700266 dev.em.0.mac_stats.bcast_pkts_recvd: 21448 dev.em.0.mac_stats.mcast_pkts_recvd: 1334 dev.em.0.mac_stats.rx_frames_64: 5590389 dev.em.0.mac_stats.rx_frames_65_127: 12234066 dev.em.0.mac_stats.rx_frames_128_255: 882048 dev.em.0.mac_stats.rx_frames_256_511: 239892 dev.em.0.mac_stats.rx_frames_512_1023: 8548498 dev.em.0.mac_stats.rx_frames_1024_1522: 205373 dev.em.0.mac_stats.good_octets_recvd: 7051893659 dev.em.0.mac_stats.good_octets_txd: 17847873333 dev.em.0.mac_stats.total_pkts_txd: 27183553 dev.em.0.mac_stats.good_pkts_txd: 27183553 dev.em.0.mac_stats.bcast_pkts_txd: 429 dev.em.0.mac_stats.mcast_pkts_txd: 599 dev.em.0.mac_stats.tx_frames_64: 9427391 dev.em.0.mac_stats.tx_frames_65_127: 3163651 dev.em.0.mac_stats.tx_frames_128_255: 3203080 dev.em.0.mac_stats.tx_frames_256_511: 565954 dev.em.0.mac_stats.tx_frames_512_1023: 185206 dev.em.0.mac_stats.tx_frames_1024_1522: 10638271 dev.em.0.mac_stats.tso_txd: 0 dev.em.0.mac_stats.tso_ctx_fail: 0 >How-To-Repeat: Connect the interface to a gigabit network. >Fix: Using the interface at 100baseTX. >Release-Note: >Audit-Trail: >Unformatted:
