It's not that simple. On the lower-end models, the on-SoC RTC is the only RTC there is. If it were disabled, there would be no RTC available at all, so there would be no preservation of time-of-day across reboots. On the Pro models, the battery backed RTC is fitted. However, the battery backed RTC has no wakeup facility. Only the on-SoC RTC has that ability, so in order to perform time-based wakeup, the on-SoC RTC needs to be synchronised with the current ToD and its alarm set. Not having the on-SoC RTC enabled means that there is no ToD based wakeup possible. -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
