Hi guys,
so I'm seeing this funny thing where an EFI region changes when we enter
efi_enter_virtual_mode when booting with edk2 on kvm. Here's the diff:
--- before 2013-07-31 22:20:52.316039492 +0200

That second boundary of region mem11 suddenly changes *before* we merge
the regions. edk2 bug?
Whole dmesg attached.
