Comment 28 for bug 1246236

Oh, I'm mistaken -- it's exactly the same as before. I hadn't noticed that the machine had replied once before going offline.

Gavin looked up the ARP issue and it turns out that pxelinux doesn't respond to ARP when in the keyboard read loop and when in the tftp send/recv loop, so that's why there's no ARP response. But I wonder, could the issue here be that the ARP cache is being blown away for some reason? While the transfer hung, I looked at the arp cache and it had an <incomplete> entry.
