Output of `acpidump`
this smells like an AML issue to me.
Method (ADJP, 1, Serialized)
{
...
Local6 = \_PR.CPU0._PSS ()
Local2 = SizeOf (Local6)
PSSN = (0x80000000 | Local2)
...
}
_PSS returns a package, I don't know if we can use AML in this way or not.
and Local6 seems to be related with the error messages

Erik, could you please confirm?
We've seen this before and we are trying to reproduce this right now... Hi Paul, Do you see this error when you boot 4.16? (In reply to Erik Schmauss from comment #5) > Do you see this error when you boot 4.16? No, I do not. We are still trying to reproduce this problem. Created attachment 275757 [details]
add package init for load operator
Here's a patch that should fix the issue. Please test it and let us know if it works for you.
