At early boot the kernel would panic with: panic: running without device atpic requires a local APIC on UEFI systems To recover a system in this state, at loader prompt, use: unset hint.acpi.0.disabled boot (I think core.lua should be modified to be compatible with an older UEFI payload, possibly issuing a warning that gets logged; and this should be mentioned in UPDATING)I just pushed https://cgit.freebsd.org/src/commit/?id=f213da893ca8c7c76e1656b36d3a10f93f9a1760 <https://cgit.freebsd.org/src/commit/?id=f213da893ca8c7c76e1656b36d3a10f93f9a1760> which should fix the issue for x86, with an UPDATING entry for aarch64.This is at best a stop-gap kludge. The real solution would be for loader.efi to publish a list of interfaces it implements and then the lua code can cope with old/new better.
Yeah I think it (I assume you mean https://cgit.freebsd.org/src/commit/?id=0abe05aeac29d99786401b9078e97dcead35f7f3 ) should be sufficient for x86 systems to boot. Thanks!
