I am using nfe on 6.3 amd63 system with the code from here: http://www.f.csce.kyushu-u.ac.jp/~shigeaki/software/freebsd-nfe.html Everything is OK except for one small, but annoying problem. Sometimes when my system hangs and I have to use reset button, nfe stops working after reboot. ifconfig shows proper status and medium, there are no kernel error/debug messages, on the surface everything seems good. But if I try to ping a machine connected to the same switch I get "host down" responses. So, no network at all. Unloading and reloading if_nfe module doesn't help, various ifconfig re-configurations do not help too. Although, if I do power off and then boot, everything is perfect again. Until a couple of weeks ago I used 6.2 amd64 and nve (patched to recognize pci id of this card) and I never had such a problem. To un-enlightened me it seems like some resetting/re-initialization of the card is not done properly by nfe. Additional info. dmesg: nfe0: <NVIDIA nForce 430 MCP13 Networking Adapter> port 0xc800-0xc807 mem 0xfe02b000-0xfe02bfff irq 23 at device 20.0 on pci0 miibus0: <MII bus> on nfe0 e1000phy0: <Marvell 88E1116 Gigabit PHY> on miibus0 e1000phy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX-FDX, auto nfe0: Ethernet address: 00:18:f3:d4:43:1e nfe0: [FAST] ifconfig (output is the same in both working and non-working cases): nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> inet 10.2.1.87 netmask 0xfffffc00 broadcast 10.2.3.255 ether 00:18:f3:d4:43:1e media: Ethernet autoselect (1000baseTX <full-duplex,flag0,flag1>) status: active pciconf: nfe0@pci0:20:0: class=0x068000 card=0x816a1043 chip=0x026910de rev=0xa3 hdr=0x00 vendor = 'Nvidia Corp' device = 'MCP51 Network Bus Enumerator' class = bridge P.S. as always with network issues, I understand that it may be not so simple, e.g. some interaction between the card and the switch, etc. -- Andriy Gapon
