Comment # 1 on bug 1205978 from Joey Lee

After bisecting, found the issue patch:

commit ecb778d0ac62560aa172786ba19521f27bc3f650 (HEAD) 
Author: Gerd Hoffmann <kraxel@redhat.com>

    OvmfPkg/PlatformInitLib: dynamic mmio window size

    In case we have a reliable PhysMemAddressWidth use that to dynamically
    size the 64bit address window.  Allocate 1/8 of the physical address
    space and place the window at the upper end of the address space.

I will revert this patch from edk2-stable202211 ovmf in openSUSE:Factory first.
