[systemd-devel] kernel failing to boot

Hello,

I am experimenting with systemd on redhat 6.

I have built 2 custom kernels:
   1. one is essentially a desktop kernel (essentially a fedora kernel)
   2. one is a stripped down kernel with many things removed.

on a normal redhat 6 box both of these kernels work without issue.

on my test systemd boxes only the desktop version is working, it fails
with the following, and drops to a shell:

Please see below for relevant outputs.

My question is what kernel options are explicitly needed for systemd

if needed i can supply my kernel configs as well.

version systemd-36
