^^^^^^^
That's a region of memory right before the 640K mark,
and your BIOS is trying to use it. This used to work,
but revision 1.544 of src/sys/i386/i386/machdep.c moved
the code that mapped in those pages until *after* they
need to be used. I (unsuccessfully) petitioned the
committer who made the change to revert it, so for now
you'll have to manually remove it, being careful not to
step on the changes introduced in revisions 1.545 through
1.547.
