igb stops to work. saing 'No bufferspace available'
no messages in /var/log/messages.log, /var/log/console.log, dmesg is empty

tcpdump -n -i igb0 shows nothing.

pull out LAN cable from igb0 card:
# ifconfig igb0
igb0: flags=8d43<UP,BROADCAST,RUNNING,PROMISC,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=401bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,VLAN_HWTSO>
        ether 00:1b:21:45:da:b8
        inet6 fe80::21b:21ff:fe45:dab8%igb0 prefixlen 64 scopeid 0x1
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active

but expected: 'status: no carrier'

other interface in system re0 continue to work fine.

CAn you help me what is wrong?
