As per PAPR specification whenever system is running on UPS we have to wait for predefined time (default 10mins) before initiating shutdown.
We have user space tool (rtas_errd) to monitor for EPOW events and initiate shutdown after predefined time. Hence do not initiate shutdown whenever we get EPOW_SHUTDOWN_ON_UPS event.
