With Linux 4.17-rc1, the message below is new on the TUXEDO Book BU1406.

Searching for the error, I only found a FreeBSD thread [1].

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

Hi Paul,

Do you see this error when you boot 4.16?
