The architects will have the correct answer of course. >From my reading of the papr, I've got the impression that there are two possibilities. First, the os-term never returns, and it's up to the service processor to do whatever it's going to do. (call home, dump, something else). Nothing we can do there. Second, os-term returns, and it's up to the OS to call into power-off or system-reboot. I think this is more likely. I havn't followed the path back from machine_restart to see exactly how we got there, but probably means a bit more logic to decide whether to call into rtas_restart() or pSeries_power_off() after the call to machine_shutdown. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
