Comment 16 for bug 71212

as a follow up, looks my problem is solved... I was using a DFE-530TX+ adapter which uses the 8139 driver. I switched, and am now using the internal intel ethernet adapter that comes on my motherboard, and all looks well. What tipped me off was that I retried the operations I was doing, but instead of using nfs, I sftp'd from my source machine over to my machine. The machine froze in the middle of a hugh file. In searching for 8139, I found where the machine locking up is a known problem.
