There is a bug report for this - looks a bit quiet now so might be good if you add some details and hopefully get it moving again.

Might be worth your while looking at some of the timed profile apps available (can't remember any at the moment) - install one and get the profile to change to a full, normal profile (online) about 10 minutes before the alarm is due. That might wake the system up and give it time for a cuppa before it has to do its next job. Worth a try.
