Hmm. That seems to be the cause of this annoying new message:

    ...

"pci=nocrs" and report a bug

which doesn't seem to hinder anything from working, but is extremely
annoying because it's printed out as some super-important "KERN_ERR
message of Doom!"

I don't see why incomplete ACPI tables would *ever* be "KERN_ERR"
level messages, but I particularly don't see it when it seems to be
our own meaningless fake entries.
