please don't resolve this bug. it is a bug that is important to know about!

If you configure an RTC alarm using the userspace-exported RTC interface, this
alarm is not persistent, i.e. if the application that set the alarm exit's, the
alarm is gone.

If I understood it, Harald means that we only set the soft alarm and it may not get through to "hwclock" RTC in PMU, it is indeed important to check for GTA02.

People are able to use the RTC alarm stuff to wake from suspend now with a commandline utility that definitely exits before the suspend. So it's definitely persistent now.
