just found Network Adapter Driver for PCI-E Gigabit Network Connections under
Linux*
version 1.2.20
Intel's Readme suggests that this will fix the driver generated interrupts.
Since our e1000e driver is only version 1.0.2 I'm going to winscp the tarball
provided by Intel to the machine and follow Intel's instructions for
installation.
Intel's website;
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=YDwnldID=15817
suggests that this version of the driver is valid for the Intel® 82571EB
Gigabit Ethernet Controllers we're working with.
I'll update this email thread when I'm finished.
thanks again,
Stephen Palmateer

Subject: Detected Tx Unit Hang Issue
Hello All,
I would like to report a problem with the e1000e driver on a CentOS 5.4 machine
with a custom kernel.
Experiencing interface timeouts/failure on a regular basis, rendering the
management interface useless.
Seeing the following error repeatedly in dmesg and stdout:
:04:00.0: eth0: Detected Tx Unit Hang:
TDH 143
TDT 12e
next_to_use 12e
next_to_clean142

The wierd part is eth2 has far more traffic on it and is not seeing any issue.
I'll try to provide as much info as I can below.
