When you ask a question on a Friday during the summer and
don't get a reply as quickly as you wanted, that means nothing.

qemu simulates a PC.  The i368ex is not a PC board and thus
the RTEMS app is accessing memory that isn't there.

To experiment with qemu/x86, you need to use the pc386 BSP
or a variant of it.

Also depending on the version of qemu you use, I have seen
cases where it does a similar fault on the boot floppy with
grub that has worked for years.
