you need the fixeep.sh script to help fix your eeprom, this is a common and 
well known issue with the supermicro hardware.
will find the script and attach it for you

the hang is caused by a bad eeprom bit. A script that fixes it for 82573-series with 
eeproms that need this bit fixed is attached to the bugreport. It detects the proper 
chipset and patches if required (uses ethtool).

Those third party card makers, they always mess up the eeprom
making things hard to support. :-)
Comment 8 Pawel Staszewski 2006-11-03 03:10:30 UTC 
ok thanks it's working now.
Comment 9 Jesse Brandeburg 2006-11-03 09:34:34 UTC 
please reopen or file a new bug if you have issues, thanks for reporting!
Comment 10 Yavor 2006-11-08 05:16:34 UTC 
Hi!
I have the same problem with this chipset (82573E), 
the script fixed the eeprom and now it is saying that it is ok:
./fixeep eth0
eth0: is a "82573E Gigabit Ethernet Controller"
This fixup is applicable to your hardware
Your eeprom is up to date, no changes were made

But the problem still persist :

NETDEV WATCHDOG: eth0: transmit timed out


The machine is SuperMicro server with 2 Gigabit Ethernet cards with the
same chipset:
0d:00.0 Ethernet controller: Intel Corporation 82573E Gigabit Ethernet 
Controller (Copper) (rev 03)
0e:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet 
Controller

There is no problem with the second card (82573L). This mesagges are only for 
the first card.
Comment 11 Jesse Brandeburg 2006-11-29 14:19:37 UTC 
Please send the ethtool -e output for your failing nic, and you may want to
enter a new bug instead of hijacking this "fixed" one.
Comment 12 Yavor 2006-11-30 04:02:01 UTC

If writing in this "fixed" bug is a problem, I can open a new one.

Hi; After rebooting the server there is no drops. Sorry for the inconvenience.
Comment 14 Jesse Brandeburg 2006-12-18 14:56:15 UTC 
user seems to have solved the problem with fixeep *and* a reboot.  closing.
Comment 15 Menny Hamburger 2007-01-02 02:48:02 UTC 
I have two machines connected via crosover cables.
I am using Quad port 82573EB cards.
I am using version 7.3.15 of the driver and bonding.
Every 2,3 reboots a simple flood ping fails with ~2-8% packet loss.
I fixed the fixeep script to include this card, but trying to run it over my 
NIC's shows that the eeprom is already updated.
Comment 16 Menny Hamburger 2007-01-02 02:56:33 UTC 
A clarification:
The problem happened on a machine with RHEL3U7 kernel.
Comment 17 Menny Hamburger 2007-01-02 03:26:58 UTC 
The card is actually 82571GB and not as specified before.
Sorry.

M.
Comment 18 Menny Hamburger 2007-01-02 04:18:27 UTC 
From doing additional dubug I am not so sure this is the same bug - please re-
close it and I will open a new bug when I understand what is going on
Comment 19 Jesse Brandeburg 2007-01-02 08:25:03 UTC 
you should definitely not update your 82571 eeprom, it would most assurredly 
be wrong.  Closing again as requested.
Comment 20 Auke Kok 2007-01-18 11:01:33 UTC 
full fix (including fix script) for this 82573 & documentation for reference is
