CPU Sleep state

I have scheduled a firmware update for 30minutes. And my system goes in to LPM (idle state2 deep) in 10 minutes 

Mostly, the update gets triggered on exact scheduled time and device comes out of LPM. But at times, the update is getting delayed. From logs I can see that CPU is getting awake. (Basically, I'm trying to print the time every two seconds which stops when system goes to LPM but in 5 minutes it again prints it, stops and again prints in 5minutes and finally causes the delay) . Is my CPU getting awake? But the device is not coming out of LPM then what is making CPU awake?
