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?
