Intel Dual port pro/1000: watchdog timeouts and no packets received

[Andrew Snow]

This is a very new card which I haven't seen before on the market until 
recently.

Card: E1G42ET (Intel Gigabit PCIe ET Dual Port  Adapter 82576)
Server: Supermicro X7SLA-H
Operating system:  FreeBSD 7.2-RELEASE and 7.2-STABLE
IGB Drivers: 1.4.1 and updated 1.7.3 from intel website



igb0: <Intel(R) PRO/1000 Network Connection version - 1.7.3> port 
0xcc00-0xcc1f mem 
0xfe9e0000-0xfe9fffff,0xfe400000-0xfe7fffff,0xfe9dc000-0xfe9dffff irq 10 
at device 0.0 on pci1
igb0: Using MSIX interrupts with 0 vectors
igb0: [FILTER]
igb0: Ethernet address: 00:1b:21:43:2f:a0

igb1: <Intel(R) PRO/1000 Network Connection version - 1.7.3> port 
0xc880-0xc89f mem 
0xfe9a0000-0xfe9bffff,0xfdc00000-0xfdffffff,0xfe9d8000-0xfe9dbfff irq 11 
at device 0.1 on pci1
igb1: Using MSIX interrupts with 0 vectors
igb1: [FILTER]
igb1: Ethernet address: 00:1b:21:43:2f:a1

igb0 at pci0:1:0:0:        class=0x020000 card=0xa03c8086 chip=0x10c98086 
rev=0x01 hdr=0x00
     vendor     = 'Intel Corporation'
     class      = network
     subclass   = ethernet

igb1 at pci0:1:0:1:        class=0x020000 card=0xa03c8086 chip=0x10c98086 
rev=0x01 hdr=0x00
     vendor     = 'Intel Corporation'
     class      = network
     subclass   = ethernet

Card detects OK but when you assign an IP and try to ping, no packets 
are received, not even ARP replies.

This appears on the console:

igb0: watchdog timeout -- resetting
igb0: Queue(0) tdh = 9, tdt = 9
igb0: Queue(0) desc avail = 247, Next Desc to Clean = 0
igb0: link state changed to DOWN
igb0: link state changed to UP



Thanks,
