uefi boot freeze on current r266272

Hi all,

I've been trying to test out the latest uefi images on a desktop with an
Asrock Killer Z87 mobo and a Lenovo L440. Both computers boot into uefi but
once the kernel is loaded they freeze. On the desktop both the mouse and
keyboard are responsive, caps/num/scrl are lit. The output of the screens
can be found by the link bellow. Any tips on what I'm doing wrong are very
much appreciated.

Thanks,
Cristian
