Try this diff on sys/arch/amd64/amd64/machdep.c, diffed against the
4.6 release version (I believe you would be using an amd64 kernel).

/* Memory is otherwise reserved */
for (bmp = bios_memmap; bmp->type != BIOS_MAP_END; bmp++) {

bmp->type != BIOS_MAP_FREE)
return 1;
The in-memory copy of the BIOS memory map seems to yield addresses
that extend past the end of physical memory -- it seems the check for
BIOS_MAP_END is insufficient -- and thus yields strange values; X
wants to mmap an address and amd64_pa_used says it can't because it's
reserved, when it in fact isn't.
This is only really a workaround patch, I don't have the time and
resources yet to verify whether there's a bug in the code that
retrieves the BIOS memory map, or whether the BIOS is being iffy in
giving us the memory map, but it has solved the "Cannot map MMIO
range" problem I had earlier with my x200.
Thanks,
Dana
