Thinking about this a bit harder that PTE is invalid because bits 52-63
are not zero, which is exactly the problem you were hitting prior to
-rc2, namely that the physical BGRT address is bogus.
Can you post the EFI memory map entries from a dmesg? I just want to
make sure that it really is the BGRT address that is broken and not
something else. Also, please post the ACPI: BGRT entry from your dmesg
too. Thanks.
