hi there - i was wondering if anyone has taken a look at this issue.  I 
am still seeing these ACPI errors on recent CURRENT systems:

ACPI Error: No pointer back to namespace node in package 
0xfffff803e71fff00 (20180313/dsargs-472)
ACPI Error: Method parse/execution failed \134_SB.AC.ADJP, 
AE_AML_INTERNAL (20180313/psparse-677)
ACPI Error: Method parse/execution failed \134_SB.AC._PSR, 
AE_AML_INTERNAL (20180313/psparse-677)


I have two amd64 (skylake and kabylake) systems that are exhibiting this 
behavior and am more than happy to test patches or other things.

cheers!
