UP2 new with UEFI 5.0. I have a bare-bones UP2. My OS uses the current version of ACPICA for all things ACPI. However, it hangs deep in ACPI AML Parsing code on first reference to \SB.PCI0 during device init (executing _INI method). Is there a way to resort to a minimum set of ACPI tables? I general, ACPI implementations should always work with ACPICA. Any troubleshooting advice would be welcome.

    Has anyone else had problems with the default ACPI tables on a new UP2? This seems to be a hard failure when executing the _INI method on the first reference to the PCI bus. \SB.PCI0
