What version of GRUB are you using?
2.04-11 - so The current Debian Testing package with your patch applied. I'd avoided build grub from scratch to avoid screwing up the system but if it's just a drop in .efi binary then I can build from the vanilla tree.
That's understandable. Before switching to GRUB upstream, I would like to understand which compatible is likely not NUL-terminated.
Would you mind to apply this patch in Xen and post the full log?

Full log further bellow but it looks like it crashes while going through the a806 config space. Is this something that grub is likely to mess with or does it point to a problem with the EDK2 build? Does the build have the tables embedded in it or does it extract it from some ROM device on the board?
