I always use in my project ( see some photos in my album ) this mode. It works very stable and fine!
Resuming from suspend takes only about 1.5 seconds, but if the power failure occurred ( blackout ) during suspend state, the resuming from hibernate takes about 4 seconds.
No problem at all!!!
I think I am going to try an experiment on Saturday. See if the Car PC can resume from sleep. If this experiment works, then I am going to have to slightly redo the electrical wiring so the PC has a constant 12V power source running to USB (via 5V adapters).
