you will definitely have random reboots like regular BBBs have it. There are hundreds of posts here and I am not sure that the issue was solved in the current kernel. You can't enable 3 power sources at TPS65217 simultaneously, only two of them. You can switch off Vac input, but Vbat is always enabled. I suppose random reboots will not take place if you physically disconnect Vac and USB0_VBUS.
