e1000 fails to load sometimes: The EEPROM Checksum Is Not Valid

e1000 fails to load sometimes: The EEPROM Checksum Is Not Valid

[Jeremy Fitzhardinge]

With 2.6.17-rc5-mm2 (and other kernels), the e1000 fails to load 
sometimes, with the message:

Intel(R) PRO/1000 Network Driver - version 7.0.38-k4-NAPI
Copyright (c) 1999-2006 Intel Corporation.
ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 20
PCI: Setting latency timer of device 0000:02:00.0 to 64
e1000: 0000:02:00.0: e1000_probe: The EEPROM Checksum Is Not Valid
e1000: probe of 0000:02:00.0 failed with error -5


Sometimes it will do this after several modprobe/rmmod cycles, and then 
it will load OK.  Once loaded, it seems to work perfectly.

This is this built-in e1000 in a Thinkpad X60:

Sorry for the long wait, there's some new information on this that just this 
morning arrived.

We received reports from SuSE that on a T60 they were seeing the same problem. 
After obtaining a T60 ourselves we managed to spot the suspected problem: it 
is related to the "smart power down" capability of the PHY. Lenovo had this 
feature turned on in certain BIOS'es which caused the EEPROM reads to fail.

Some people reported that the problem goes away when you plug in a cable - 
this guarantees that the PHY is turned on and probably masks the issue for a 
lot of people (either you work plugged in or forget about the NIC when you 
work wireless, thus not seeing the issue).

The latest EEPROM's from Lenovo (obtainable from their websites as .iso) seem 
to have this feature turned off, which resolves the issue.

We're right now working on seeing if we can find a workaround for the issue 
ourselves in the driver, but in any case you can always try to grab the latest 
BIOS from lenovo's website, and tell us if that works for you.

meanwhile we're working on a more permanent solution.

Cheers,

Auke

Do you have a specific link to this update?  I can't see anything 
obvious on their site relating to this.

See:

http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-63027

links to the latest .iso image.

Note: I haven't tried the 1.07 update myself. I had to *downgrade* our test 
system to actually expose the bug.

This appears to be a link to the T60 1.06 update.  Do you know if 
they're planning an X60 update too?

x60 bios upgrade 1.06 is here: (found by typing "x60 bios" in the search bar 
on the same website)

http://www-307.ibm.com/pc/support/site.wss/license.do?filename=mobiles/7buj04uc.iso

unfortunately the changelog for this BIOS upgrade doesn't tell us much if the 
DSPD feature was affected or not. I also have not tried this one either.

I've been running 1.06 for a while, and I haven't seen this problem in a 
while, but I can't say if those two observations are correlated.
