>Description:
The ACPI subsystem should not go into sleep mode once we started system shutdown. We can accomplish this by disabling system shutdown in rc.shutdown.
>How-To-Repeat:
To reproduce try setting hw.acpi.lid_switch_state=S3 and then shutdown the system. While the system is shutting down, close the lid. The system will sleep, which doesn't make much sense at this stage.
