[Bug 1675522] Re: arm64: Synchronous Exception at 0x00000000BBC129BC

[dann frazier]

Because the issue is difficult to hit - and therefore bisect - I ended
up using 10 VMs in a reboot loop. Turns out even with the latest edk2
source, I could hit a boot-time crash. So I dug a little deeper and
found that the crash I'm seeing w/ latest edk2 is actually in shim code.
We didn't yet build shim for arm64 in zesty, so it's likely not the same
bug I reported here[*], so reported it in new bug 1928010.

[*] Although it is possible that the bug is in some common code that
impacts both shim and GRUB (e.g. gnu-efi)

Bug description:
  I installed a KVM VM with the zesty beta server ISO. The install went
  well but, upon reboot, GRUB entered a Synchronous Exception loop after
  selecting the Ubuntu boot option.

  After killing qemu-system-aarch64 and restarting the VM, the system
  booted to a prompt w/o issue.
