- We tried setting an alarm (3 minutes in the future) echo 0 > /sys/class/rtc/rtc0/wakealarm echo `date '+%s' -d '+ 3 minutes'` > /sys/class/rtc/rtc0/wakealarm
or echo echo `date '+%s' -d '+ 3 minutes'` > /sys/class/rtc/rtc0/wakealarm - powered down the machine and it bootet up after the time - Now we see [ 2.261416] rtc rtc0: invalid alarm value: 1900-1-29 1193038:40:16 in the kernel-log again - Machine will not power down until alarm is newly set right or unset!!! You have to unplug the powercable
