Ours however, did not boot and we isolated the problem to be a memory problem: When we plug in 4 GB or more, Grub2 fails (when you finally type "boot" on the command line, the machine instantly reboots). If we remove all but 2 GB of RAM, it works and we managed to boot a Debian kernel. So this seems to be a bug which only appears on this type of machine with >= 4GB of RAM. Unfortunately, I haven't found a way yet to get any debug output for you from the machine (serial console doesn't seem to be supported in EFI). If there is anything we can do to get this bug solved, please let us know.

However, you're compiling it on a 64-bit kernel, right? The limitation you are talking about is the 32-bit 2 64-bit limitation. 32-bit only supports up to 3.25GB of RAM. Have you tried compiling it on 32-bit os? That may (for some reason) fix the problem. Give it a go.
