Just as an FYI, I was able to workaround the issue (temporarily until we
find the fix) by using an internal version of grub (used for NIM
installs). I netbooted my LPAR that was failing as above and used the
on-disk conf file (well, copied it to my boot-server and used it as the
netboot conf file). The system rebooted once for c-a-s negotiation, and
then successfully booted to login prompt!

So, I believe the issue is in the grub shipped with Ubuntu. I did a
quick test of setting an nvram variable at the OF prompt (ibm,fw-new-
mem-def) to true, and then booting to grub, rebooting from the grub
prompt and checking the variable again. It's value was now false. The
Linux kernel negotiates this value to true, so I think that's why we end
up in a c-a-s loop. Assigning over to Paulo for now.
