I've run into the BBB random reboot problem a while ago. We've eventually found out the root cause is the USB-OTG detection. The USB-OTG periodical probing actually caused the problem. Details and fix please the link below: https://groups.google.com/forum/#!searchin/beagleboard/unexpected$20reset/beagleboard/xPxzYyNsA78/DOlXIlyYTqIJ
However my fix was based on the 3.2 kernel. I am not familiar with the kernels you are working with. And I don't know if the USB-OTG is root cause in your case. BBB and BBW have different PMIC designs. You could take a look at the schematic. If you really want to isolate out the hardware, you can try to patch and build from 3.2 kernel to see if BBB still reboots. I have mulitple systems running for months and never had any random reboot issues. I hope this helps.
