igb on a Nehalem system, buildworld stats

[Mars G Miro]

Hi guys,

   I just got on my hands today a NEHALEM system:

2 x 5560 Nehalem CPU (2.8GHz, 8MB cache memory, 6.4GT/sec [QPI])
12GB 1333Mhz DDR3 Memory
1 x 500GB SATA HDD

  FreeBSD 7.1-RELEASE/amd64 install fine, however I seemed to be
having problems w/ its built-in Intel NICs:

igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
        ether 00:30:48:c5:db:e2
        inet6 fe80::230:48ff:fec5:dbe2%igb0 prefixlen 64 scopeid 0x1
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
igb1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
        ether 00:30:48:c5:db:e3
        inet6 fe80::230:48ff:fec5:dbe3%igb1 prefixlen 64 scopeid 0x2
        inet 172.17.32.32 netmask 0xffff0000 broadcast 172.17.255.255
        media: Ethernet autoselect (1000baseTX <full-duplex>)
        status: active

The first NIC would always want 100baseTX no matter how I'd ifconfig
down/up it, so I just had to use the 2nd NIC. Unfortunately, this too
is having problems. Like being unable to 'see' some machines on the
same network segment. Some other machines are accessible. And yes I've
double-checked the network stuff (cables, switch, IP settings) and my
conclusion is b0rky NICs.

pciconf -lvc:
igb0 at pci0:1:0:0:        class=0x020000 card=0x10c915d9 chip=0x10c98086

    vendor     = 'Intel Corporation'
    class      = network
    subclass   = ethernet
    cap 01[40] = powerspec 3  supports D0 D3  current D0
    cap 05[50] = MSI supports 1 message, 64 bit, vector masks
    cap 11[70] = MSI-X supports 10 messages in map 0x1c enabled
    cap 10[a0] = PCI-Express 2 endpoint
igb1 at pci0:1:0:1:        class=0x020000 card=0x10c915d9 chip=0x10c98086
rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    class      = network
    subclass   = ethernet
    cap 01[40] = powerspec 3  supports D0 D3  current D0
    cap 05[50] = MSI supports 1 message, 64 bit, vector masks
    cap 11[70] = MSI-X supports 10 messages in map 0x1c enabled
    cap 10[a0] = PCI-Express 2 endpoint

So anyone else having igb problems? I'm downloading 200812-CURRENT now
(is tehre gonna be a 200901-CURRENT ISO soon? :-p), I'd like to try
that, but checking cvs seem only a handful of changes.

Also I did some buildworlds:
 make -j8 buildworld
    2846.900u 2266.188s 15:50.43 537.9%     6375+2082k 10084+7937io

 make -j16 buildworld
    3518.254u 2175.593s 14:23.29 659.5%     6656+2147k 26165+8546io 4300pf+0w
 make -j32 buildworld
    3582.897u 4437.710s 18:03.88 739.9%     6528+2125k 5725+7930io 1555pf+0w
