Bug#794266: Problem resists - definitely a problem with the alarm of the rtc!

[Manuel Roeder <manuel_roeder@gmx.de>]

- 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
