Amd64x86, Intel Core 2 Duo, 2GB DD3 Ram, NVIDIA 320M GPU, 64GB SSD drive, can attach more specs if it helps.

>Description:
Trying to boot the UEFI image (from a flash drive) causes a panic.
All the default, no ACPI and no ACPI no SMP modes are affected.
The traceback in the last says:

 ----%<------------

    Panic: kernel diagnostic assertion "ucpu != VM_FREE_PAGE_TO_CPU(pg)" failed: file ~/usr/src/sys/uvm/uvm_page.c", line 862

   Fatal breakpoint trap in supervisor mode 

----%<------------

I've got a picture of the dump, can share.
PS: the machine works OK in OS X (and OpenBSD 6.1)

>How-To-Repeat:
Boot the image
