Hello,
I'm using a linux payload. Here are a few pitfalls you should mind:
* Fedora's prebuild kernel doesn't work any more. You likely want to
compile it yourself.
* Self compiled kernel does work. Tested versions are: Linux 4.1, 4.2,
4.3, 4.4
* I don't enable pre kernel GPU initialization
  The screen is black until the drm kernel module is started.
* Make sure to add support for your root filesystem (ext2/3/4 is
default)
  Others need to be compiled in, or you need to provide a initramfs
containing
  the kernel modules for the filesystem. I compiled them in, instead of
using
  a initramfs.
* Make sure to give a working root path (PARTUUID is fine, too)
* Initramfs isn't used by me, so I can't tell if it's working, but it
should.

Kind Regards,
Patrick

I use initramfs and it works wondefully well. Figures, Patrick Georgi did
that code :-)
