Sorry, I can't since I've recently switched away from my Intel Matrix RAID configuration...

Mot likely this is already fixed in current trunk. Could you confirm?

Is there any interest at all to tackle this? Am I too impatient to expect no matter what kind of reaction within a week?

I'd like to chainload Windows from GRUB2 (2.00-1 from Arch Linux repositories) and am using the following menu entry:

menuentry "Windows 7" --class windows --class os {
insmod part_gpt
insmod fat
insmod search_fs_uuid
insmod chain
search --fs-uuid --no-floppy --set=root 12c9-86c3
set debug=all
chainloader /efi/Microsoft/Boot/bootmgfw.efi
}

Booting this results in the following output. This transcribed from screen, if you require the full output, please say so and I will attach a serial cable to be able to capture it.

And then the system just stands there with blinking cursor and doesn't accept any input (this could be because of my USB keyboard, perhaps).

For reference: Windows boots without issue if I select it directly from the EFI boot selection menu.

The hd0 is a Intel Matrix FakeRAID volume.

On help-grub Jordan Uggla said that he remembers "[...] seeing a problem a while ago with Windows' UEFI boot manager failing when there was memory pressure, and FakeRAID often uses a lot of memory, with the additional memory used by grub pushing it over the edge to where Windows' boot manager fails."
