Please note, there are multiple causes of this symptom.
As posted by Dominique Gallot above, if you have an adapter (on board or standalone) based on the Intel 82573 chipset, this issue may be caused by an improper setting in the adapter's EEPROM. It will occur regardless of TSO setting, and even in the new 2.6.27 kernel shipping with Intrepid Ibex. The following document from Intel has additional information, under the section "82573(V/L/E) TX Unit Hang Messages". http://downloadmirror.intel.com/9180/eng/README.txt
