I updated my kernel to 3.15.6-bone5, just as you've said. But, as it seems, this does not fix the issue completely. What I'm observing is lack of ethernet connection after some boots. They characterise with initial hangup, I can see 'C' being put on the console until a watchdog located on cape connected to my BBB reboots the BBB. It happens on its own, without any extraordinary operation being run on this system. For example two times last night. I have to plug out and in the power cable to fix the issue, SW reboot doesn't help. Power is delivered to BBB via our cape. Another way to reproduce it is to plug out the sd card and wait for watchdog to reboot BBB. After that, 'C' are printed to the console(OS on eMMC is not bootable), and when I insert back the sd it instantly boots from it. No connection after that too. Do you have any ideas on what's going on and how to fix this? Below I'm attaching the log from this: Welcome to minicom 2.7 OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19.
