Details:

Affected GIT commit
-------------------
c291f47b2c003ef6daeafaedd458db838bad6fb8

Build system
-------------

Debian Unstable from 08 August 2014
Build options

./configure --with-platform=efi at first pass. 
./configure --with-platform=pc at second pass. 

How do I build and prepare my system
------------------------------------
Make sure no Debian grub package is found in chroot

apt-get remove '.grub.' 
Grub2 (efi+pc)) Build and installation

# Make sure we are testing the right revision 
mkdir grub_upstream 
cd grub_upstream 
git clone git://git.savannah.gnu.org/grub.git . 
git checkout COMMIT-TO-TEST 
# Remove any non git related file - BEGIN 
git reset --hard 
git clean -f -d 
git clean -f -x -d 
# Remove any non git related file - END 
# Build efi based grub and install it - BEGIN 
./autogen.sh && ./configure --with-platform=efi && make 
# Dont forget to delete any rest of previous installation - BEGIN 
sudo rm -rf /usr/local/etc/grub.d/ /usr/local/bin/grub-*
/usr/local/share/grub/ 
# Dont forget to delete any rest of previous installation - END 
sudo make install 
# Build efi based grub and install it - END 
make clean # Prepare for next build 
./configure --with-platform=pc && make # Prepare for a i386 build 
sudo make install # Install i386 build

Super Grub2 Disk build
----------------------

./supergrub-mkrescue -o="whatever-name.iso" 
You can find supergrub-mkrescue source code here: 
https://forja.cenatic.es/scm/browser.php?group_id=204 
Anyways what it is running is: 
grub-mkrescue --output=super_grub2_disk_hybrid_2.00s2.iso /tmp/tmp.As2v1yM9lK

where /tmp/tmp.As2v1yM9lK is a temporary directory with all the extra Super
Grub2 Disk files. 
Probably running: 
grub-mkrescue --output=test.iso /tmp/emptydir/ 
which needs to output both these messages: 
Enabling BIOS support ... 
Enabling x86_64-efi support ... 
should arise the same results. 

VM system
----------

Virtualbox 4.3.10 r93012 
Enable EFI option is unchecked! 
Cdrom drive: super_grub2_disk_2.00s2.iso 
Disk 1: Windows 7 
Disk 2: Rescatux USB 
Disk 3: SteamOS disk 
Disk 4: efi test 

How to reproduce the bug
-------------------------

If needed press 'c' to go to grub shell.

grub> nativedisk

What happens then
------------------

I am currently not seeing but I remember to have seen:
`hd96' disk not found


The Virtualbox Virtual Machine aborts (You see aborted next to it). There is
no important information in the Virtualbox logs.


More information
-----------------

While doing some more tests with phcoder we have kind of concluded that the
problem came from ahci.

Grub probably deals with ahci in a way that no other OS does so... it might be
that Virtualbox cannot support that behaviour.

But, actually, more information and testing is needed.
