In need to switch from a testing image to a stable image verison
Linux beaglebone 4.1.2-ti-r4 #1 armv7l GNU/Linux
BBB-eMMC-flasher-debian-8.1-console-armhf-2015-07-19-2gb downloaded from 
- HW: Beagle Bone Black Rev C
- OS: Debian 8 (jessie)
- enabled uarts by bb.org-overlays 
Random Reboots, maybe the reason are ‘Debian 8.1 / kernel 4.1.x test releases are unstable’  or ‘BBB intermittently rebooting’ .
Can i upgrade or downgrade the kernel to fix this issue? How?
I prefer this kind of solution.
Or do i need to flash another image? Which one?
Does this the work?
Flash BBB-eMMC-flasher-debian-7.8-console-armhf-2015-07-28-2gb  image
To get debian jessie: $ sudo apt-get install linux-image-armmp
Enable uarts $ git clone https://github.com/beagleboard/bb.org-overlays; cd ./bb.org-overlays; ./dtc-overlay.sh ; ./install.sh
