I'm having the same problem with an Asus P5B motherboard using
pxelinux. I guess it can best be described as "locking up" when it
exits from menu.c32/vesamenu.c32, even by timeout. If I boot the same
selection directly from pxelinux.0 (prompt or timeout), everything
works fine. I've tried several versions between 3.36 and 3.62 with the
same results. I've been using a USB keyboard, but the problem isn't
that the keyboard isn't dead.

I've watched the network from the server side using tcpdump, and the
RRQ packet is sent from the client after selecting something or timing
out from menu.c32. The server (tftp-hpa) sends back OACK, and the
client never responds. The server retries the OACK packet a number of
times.

Here are some details for the motherboard:

* Asus P5B ROM version 1803 (11/26/2007)
* Intel P965 / ICH8 chipset
* Network card identifies itself as Realtek RTL8111B/8168B Gigabit
Ethernet Controller v1.60c (050710)
* The PXE stack identifies itself as Intel UNDI, PXE-2.1 (build 082)
* Network card is PCI ID is 10ec:8168 [1043:811a]

Please let me know if any other information would be useful.
