I can reproduce the hang, both with your UEFI binary and my own release build. The debug build works fine, unfortunately...
Tianocore built from master as of today, that is.
OK, it appears that we were missing some cache maintenance. It is not obvious how that should affect A57 only, but with these patches, I can now reliably run the release version on my Seattle A57

Thanks. Do you know when there would be a new build on releases or snapshots?
Let me check with Leif. We have another candidate patch now that he could perhaps apply and kick off a build?
I now have independent confirmation (from Laszlo Ersek) that the cache maintenance patches I am proposing fix the issue on Seattle.
Which patches are those? For UEFI?
Hopefully this means Juno is fixed as well.
I am trying to get a snapshot out asap, today or tomorrow perhaps?
Thanks, -Christoffer
