I was able to gather some network traces during one of these failed installs.
The lpar stops responding to ARP requests. This appears to be the real
killer here. The boot process proceeds to the point of getting the
grub.cfg file, but the remote server's arp entry eventually times out,
and the connection stalls:
...

9834 423.498762 e4:1d:2d:10:92:40 -> ff:ff:ff:ff:ff:ff ARP 42 Who has 9.47.67.114? Tell 9.47.68.41

...
As a test, I fixed the ARP entry on the tftp/NFS server, and was able to
boot into the installer. The lpar is currently sitting in the
installer waiting for further instructions.
== Comment: #11 - Kevin W. Rudd - 2016-07-01 16:51:31 ==
This issue does seem to be specific to the grub code found in the trusty-xenial.318.39 netboot image:
http://ports.ubuntu.com/ubuntu-ports/dists/trusty-proposed/main
/installer-ppc64el/20101020ubuntu318.39/images/xenial-netboot/
Since it was reported that a 16.04.01 install worked on this lpar, I
created a hybrid ubuntu-installer directory where the ubuntu-
installer/ppc64el/powerpc-ieee1275 directory pointed to images pulled
from the following xenial image:
http://ports.ubuntu.com/ubuntu-ports/dists/xenial-proposed/main
/installer-ppc64el/20101020ubuntu451.2/images/netboot/
This hybrid netboot structure worked just fine, and grub properly
responded to ARP requests.
