So I had to end up instrumenting the EFI stub to see where the error came from. At the start of the stub, there is no GHES.2 error. The error first shows up after the stub's call to ExitBootServices returns. So it looks like the firmware itself is causing the error. There's still a chance that the stub is doing something wrong with the memory map passed to the firmware, so I'll try to eliminate that as well. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
