Some UEFI firmware implementations contain bugs that are triggered when trying to read files, using the EFI_FILE_PROTOCOL, into buffers above 0xffffffff.

This issue was reported on the linux-efi mailing list here, https://lkml.kernel.org/r/53E62EEF.9040801@gmail.com

and while we now include workarounds in the kernel, we should be checking for this bug with LUV.

The best way to detect this bug is from BITS, which runs in the Boot Services phase.
