I am using a dual port Intel NIC on an A-Bit IC7-G; any reason why I get these?
[4298634.444000] eth2: TX underrun, threshold adjusted. [4299146.645000] eth2: TX underrun, threshold adjusted. [4299146.645000] eth2: TX underrun, threshold adjusted.

I see in the mailing list archives this error was most prevalent in 2.4.
However, it also shows up in 2.6: http://lkml.org/lkml/2005/6/7/49 http://lkml.org/lkml/2004/5/19/20 http://www.ussg.iu.edu/hypermail/linux/kernel/0506.0/1512.html http://www.ussg.iu.edu/hypermail/linux/kernel/0405.2/0535.html
I am using the e100 driver, MAC addr commented out with **.

I have other boards and I do not recall seeing the message about the Receiver lock-up bug, could this be part of the reason for the TX underrun?
Does it matter which PCI slot I place this card in? It is currently right next to a PCI 3com 509 (thinnet).

Would increasing the txqueuelen fix this issue? Or should I replace the NIC to get rid of these messages?
Any help would be much appreciated.
Thanks,
Justin.
