The second error message:

FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: 
[77191.628769] ACPI
Error: Method parse/execution failed [\_SB_.PCI0.SBRG.LPTE._SRS] (Node 
ffff88002cfc0488),
AE_AML_BUFFER_LIMIT (20110623/psparse-536)

ADVICE: Method failed: ResourceSourceIndex is present but ResourceSource
is not.

This is the ACPI interpreter noting that the CreateByteFields() are
overflowing the short buffer and this trips this subsequent AML BUFFER
LIMIT (i.e. overflow) error.  The ADVICE from fwts is not helpful, I
will check why that is less than helpful.

So, as it stands, I think we have a firmware bug.  The PCI _SRS is not
functioning correctly, we may be seeing the link control being set
incorrectly, so we may have some underlying PCI issues when doing S3 at
the worst case.  So I suggest this needs fixing.
