http://wiki.openmoko.org/wiki/Qtopia_on_Neo_1973#Suspend_issues ---use u-boot to remove the console= boot variable, makes the console stop interfering with gsmd (since, on the hardware level, they use the same uart) http://labs.trolltech.com/blogs/2007/12/04/neo-neuros-and-other-things/ """The problem was that suspending would cause the modem to start spitting out junk. and so would not respond to a modem wake up or be able to make phone calls after resuming. The fix is a bit odd, really. I just delete the /dev/ttySAC0 (modem) device and then create it again right before I power up the modem. So now, that aspect of suspending/resuming is working, at least on the one phone I have. Well, for the first suspend anyway.""" You should note that suspending also makes gsmd stop listening to the gsm modem, so it's either battery-life or phone. I don't know how they are planning on fixing this, but it would have to be something similar to ethernet wake-on-LAN. As a temporary hack, I've got a USB charger (like http://www.ladyada.net/make/mintyboost/, though I'm ashamed to admit that mine is a pre-made Noma one) that I wander around with. I haven't tested it all out in rugged conditions yet, but I imagine I could get by for at least a day. -Nick
