[Bug 30476] Re: e1000_clean_tx_irq: Detected Tx Unit Hang

[Dominique Gallot]

Text copy from the e1000 website:

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.

See : http://e1000.sourceforge.net/wiki/index.php/Issues#82573.28V.2FL.2FE.29_TX_Unit_Hang_messages
Run the script fixeep-82573-dspd.sh in order to fix the problem !
