I've searched for this and haven't found and answer. My 770 is working pretty stable on 2007 with stock kernel (fastMMC made it reboot frequently), have the frequent 'desktop' crash were the desktop restarts with no applets running but that happens only when taxing the machine. The problem is when I connect the charger. In anywhere from 15 minutes to an hour at most, the unit reboots.
Is anyone else experiencing the same? Or should I just install from scratch and hope it won't happen again? I boot 2007 from the MMC card and keep 2006 on the internal flash. When booting 2006 I have no issue when charging.
