UEFI boot failure: BIOS smap did not include a basemem segment!

[Jean-Sébastien Pédron]

Hello!

I tried the following FreeBSD snapshot on my Clevo W860CU with UEFI
enabled:
FreeBSD-11.0-CURRENT-amd64-20140903-r270990-memstick.img

The boot fails early with the following error:
panic: BIOS smap did not include a basemem segment!

The full picture of the panic is here:

Here's a video of a verbose boot (the quality is really low, I can try
to redo it if this one doesn't help):

When I tried UEFI a couple years ago (with Windows 7), it could boot.
