You wrote: "Although the shutdown issue disappeared after reinstalling the entire system my NAS would still occasionally boot and immediately shutdown for no obvious reason. A second boot would bring the system up as expected, but it was annoying nonetheless." I have no explanation for this behavior. What do you mean saying "immediatly shutdown"? Is this like a power off, or a clean reboot like "init 6"? And I don't see what a reboot would change for the rtc chip that I would expect only be able to wake up the machine but not shut it down. Do you have a boot log? Can you reproduce the problem, e.g. by setting the alarm: echo +150 > /sys/bus/i2c/devices/0-0030/rtc/rtc*/wakealarm and then wait 3 minutes. If yes, goes the problem away after: for i in +150 0 +150 0; do echo $i > /sys/bus/i2c/devices/0-0030/rtc/rtc*/wakealarm done instead of the i2cget command? On a side note I also don't understand why reinstalling the NAS changes anything. Does the installer access the rtc other than setting the time? Best regards Uwe
