I can reproduce it on a pure Debian Jessie system. It works with the
patch and without OVMF but not with OVMF, after the "Windows loading
files" finishes it just resets the VM.

So on Arch I have no problems but on Debian. Kernel 3.16 vs 4.5 and Gcc
4.9 vs 6.1. OVMF was the same version on both, namely 26bd643 pure (from
your repo).
Although the Debian based Proxmox VE Distro has Kernel 4.4  (Ubuntu
Kernel) and there it doesn't works also, GCC is the same there (just for
info).

The used Kernel:
Linux debian-pure 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2
(2016-04-08) x86_64 GNU/Linux
