Your dmesg shows that this is the same thing we found broken for Dells:

Here is the bug info.  Note that Luming's patch does NOT fix the problem
but just silences the warnings.  If you use the ASL patch I have attached
that adds RefOf/DerefOf (credit Mark Santcroos), the problems are fixed.
You can also revert dsmthdat.c back to what it was pre-0619 and that also
fixes the problem.

The issue is, ACPI-CA is still not getting its argument-passing right
after moving away from "always copy" semantics.
