Christoper, I reviewed my syslog concerning all Kernel-->ACPI logs via: cat /var/log/syslog | grep kernel | grep ACPI
I have 2 questions and hope you can help me understand: 1. ACPI loaded the 8 SSDT tables. I assume these equate to the ssdt1.dat to ssdt8.dat files obtained from acpidump. However, ssdt9.dat to ssdt12.dat were not shown to be loaded. Why did it not report 4 table load failures but 1 in the ACPI Error? Below are the relevant tables reported in my syslogs?

The ACPI Error concerning \_SB_.PCI0.XHC_.RHUB.HS11 Namespace lookup failure said dswload is affected. I understand dsw to mean "Device Sleep Wake". Does this mean the Namespace lookup failure caused the following pci device System wakeup to be disabled?

Based on what I have learnt from ACPI, acpitool -w and lspci, I think the error is related to Namespaces provided in the DDST on \_SB_.PCI0.XHC_.RHUB.HS11, which I think concerns the Root → System bus tree → PCI bus → USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) in my system. I have not found what .RHUB.HS11 refers too. I have tried changing my UEFI USB settings but to no avail. Appreciate help to fix this bug.
