UEFI, iPXE, and HP Service Pack for ProLiant (SPP)

[fdge]

I am trying to deploy SPP over the network using EFI, it works when in legacy mode, but soon we will be switching over to EFI. The servers are ML110s, ML350s, DL380s, and more...

The current message that keeps being displayed is:

Code:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
CPU: 0 PID: 1  Comm: swapper/0 Not tainted 3.12.38-44-default #1

SPP is 2016-10

iPXE is compiled from git source on 2017-01-17 build 26050

I also tried chainloading:
syslinux.efi, it crashes.
elilo reports token is too long.
grub2 is unable to get an IP address, and using a static IP is not a reasonable option because more than one server will be running SPP and there is more than one subnet.

the ipxe menu contains:
