You are right, Eric!

I've recompiled igb driver to see driver load progress with faulty chip 
id:
pcib5: <ACPI PCI-PCI bridge> irq 47 at device 3.0 on pci0
pci5: <ACPI PCI bus> on pcib5
igb0: <Intel(R) PRO/1000 Network Connection, Version - 2.5.3-k> port 
0x2020-0x203f mem 0x91920000-0x9193ffff,0x919c4000-0x919c7fff irq 40 at 
device 0.0 on pci5
igb0: Using MSIX interrupts with 9 vectors
igb0: The EEPROM Checksum Is Not Valid

So the reason is broken card's EEPROM. But i don't know how it might be 
happend.

Thanks for your assumption.


|Igor,
|
|A red flag is that it doesn't have an entry in the pci ids database, even

|
|I think something is wrong with your card.
