I had a successful boot on my BBB, and then managed to login, but then device started hanging. I plugged in the serial console cable and saw the below error in the console. After some time, maybe about 5 min, the system un-hung. Kernel version: 4.4.54-ti-r93. Appreciate if there are any pointers. Thanks
