Kernel keeps crashing. I’m rebooting it every four hours to keep it alive and it works at some extent. Nonetheless when heady disk job kicks in, you cannot seem to stay away from crash. It’s lucky to capture any crashlog. Most of times, a crash takes down the system with it.

Kernel version : 4.4.8-armada-17.02.1-gb8d7d22 #1 SMP PREEMPT

Here’s a crash log (The previous one was in reverse order, and this is in normal order.)
