No. It is the second half of S5. When we go from the boot kernel to the restored kernel I am talking about. That path is exactly what happens successfully in the kexec case. Transitioning from one kernel to another. If that path works reliably in kexec then we are talking about something that can be solved without respect to any specific ACPI implementation.
