I've been trying to test a boot loader on my MinnowBoard Turbot board.
It's running the latest 1.0 firmware from firmware.intel.com, and I'm
seeing a hang at the point when gBS->ExitBootServices is called.
The last debug output is:
ConfigSccBootableDevicesAtExitBootService() End

The X64 firmware works fine: the boot loader finishes and the kernel
starts running.
I looked to see where ConfigSccBootableDevicesAtExitBootService might
be, and unfortunately it seems it's in one of the binary modules.
The code for the boot loader is in
https://svnweb.freebsd.org/base/head/stand/efi/loader/bootinfo.c?revision=338022&view=markup
.

I did more debugging using OVMF and found that the i386 boot loader code
was trying to call printf (which allocates memory) after
ExitBootServices. And that booting an i386 kernel isn't actually
supported. So there's not a problem with the MinnowBoard firmware.

Hi Rebecca,
MinnowBoard Turbot Dual Ethernet runs with UDK2018
https://github.com/MinnowWare/UDK2018-MinnowBoard
That BIOS starts a 64Bit Windows10, including S3 and resume…
