Problem solved/fixed:

Remember to give loopback a ip address like this:

ifconfig loopback 127.0.0.1 255.255.255.255

and then run dhcp like this example:
dhcp eth-pci(0,16,0)

I am reopening this issue to add a patch to the 'dhcp' command.

If you run 'dhcp' before the loopback interface is configured with IP 127.0.0.1, the network layer gets into a strange state that (AFAIK) is only cured by a reboot. This patch avoids this by having 'dhcp' explicitly check that the loopback interface has '127.0.0.1' as one of its IP addresses. If not, it gives up with an informative message.

Applied patch and marked this issue as fixed.
