e1000e EEPROM corruption

e1000e EEPROM corruption

[Karsten Keil]

Hi,

so after this ugly bug is finally fixed, here maybe left some victims of
this bug.

If here is still sombody who need help to recover from this issue,

I can probably help him, I successful recovered all machines on our side,
even one which do not longer show the NIC via lspci, so the only restiction
is, that the machine still boots and we have a NVM image of a similar
machine.
You should know the PCI ids of the NIC from the time before it crashed and
the MAC address.

I need some assistance here. Machine is a Thinkpad R61 and the device
has fallen off the bus. It used to be at 00:19.0:

00:19.0 Ethernet controller: Intel Corporation 82566DC Gigabit Network Connection (rev 03)

I can get my hands on a NVM image from an identical machine during the
week.

Hi,

The thread on the list is quite old, but I think I have the same problem 
problem on
Toshiba Tecra M5 laptop with 82573L Gigabit Ethernet Controller runling 
Linux 2.6.38-rc5.
I can see this:
e1000e 0000:02:00.0: (unregistered net_device): The NVM Checksum Is Not 
Valid
when I try to load e1000e module.
Ethernet controller is visible in lspci output.

I had such problem few times earlier but it used to disappear after few 
hours.
Now the network card don't like to work from two days.

When I try to remove NVM check from the driver code the driver says:
(unregistered net_device): Invalid MAC Address: 00:00:00:00:00:00
So I assume that there are zeros in EPROM of my network adapter.
I can not use ethtool to read or write EPROM of my card because there is 
no eth0 device.
I have access to the same laptop, so I can get correct EPROM contents.
Still I don't know how to put this to my card.

Could you tell me how to reprogram my card?

Regards,

Maciek

Looks like a hardware issue to me. Cold/broken solders (reflowing the board
could fix it), for example.

That would only help if the problem is a "weak programming" of the EEPROM,
which is something I have never seen before.  Writing to it with flacky
circuitry is probably going to crap it for good.

I found the way to run my network card without writing anything to EEPROM.

I removed NVM and MAC address checks from e1000e driver source.
The module loads fine. Ethernet adapter have MAC 00:00:00:00:00:00.
Than I change MAC to correct one by ifconfig eth0 hw ether.
Network works fine. I could even read correct data by ethtool -e.
It makes the problem more strange. The correct EEPROM is there but...
