Generally a hardware issue. Most likely a bad cable, could be a bad NIC or bad switch port.

Cool Read This!!!!!!!!!

It worked for me after days of searching!

let me know please if it helped you to....

Since i am unable to post links yet: e1000.sourceforge.net/doku.php?id=known_issues&DokuWiki=f0b1bbe161d58fa8ae4d5a737225f5aa

82573(V/L/E) TX Unit Hang messages
Several NIC's with the 82573 chipset display TX unit hang messages during normal operation with the linux e1000 driver. The issue appears both with TSO enabled and disabled, and is caused by a power management function that is enabled in the EEPROM. Early releases of the chipsets to vendors had the EEPROM bit that enabled the feature. After the issue was discovered newer adapters were released with the feature disabled in the EEPROM.
You can test whether your system is affected by this bug using the script found on the Tx Unit Hang page.
If you encounter the problem in an adapter, and the chipset is an 82573-based one, you can verify that your adapter needs the fix by using ethtool:
# ethtool -e eth0
Offset Values
------ ------
0x0000 00 12 34 56 fe dc 30 0d 46 f7 f4 00 ff ff ff ff
0x0010 ff ff ff ff 6b 02 8c 10 d9 15 8c 10 86 80 de 83
^^
The value at offset 0x001e (de) has bit 0 unset. This enables the problematic powersaving feature. In this case, the EEPROM needs to read df at offset 0x001e.
A one-time EEPROM fix is available as a shell script. This script will verify that the adapter is applicable to the fix and if the fix is needed or not. If the fix is required, it applies the change to the EEPROM and updates the checksum. The user must reboot the system after applying the fix if changes were made to the EEPROM.
Example output of the script:
# bash fixeep-82573-dspd.sh eth0
eth0: is a "82573E Gigabit Ethernet Controller"
This fixup is applicable to your hardware
executing command: ethtool -E eth0 magic 0x109a8086 offset 0x1e value 0xdf
Change made. You *MUST* reboot your machine before changes take effect!
The script can be downloaded here (fixeep-82573-dspd.sh).

I really doubt this thread is even relevant now, it was started in 2005 and any problems extant then are likely to no longer exist.
