As I reported here (https://github.com/armbian/build/issues/1230), I'm seeing frequent reboots and Kernel Panics on a RK3399 board while running ElasticSearch, a kinda heavy application that runs on Java.
I currently run a Kubernetes cluster on two RK3399 boards (NanoPC-T4). One of them I has a version of DietPi with a Kernel 4.4.138 compiled by myself. and runs perfectly. The other had a newer version of a Kernel (4.4.154) also compiled by me and that's where I started seeing the reboots.
After this, I installed Armbian thinking it might be something with my DietPi distro. I installed 5.69 with Kernel 4.4.167 and saw the same problems. I did a full memory test with *memtester* and found no errors.
After I reverted this board to the same 4.4.138 and it's DTB, the board is stable again. I can provide the DTB and Kernel I used that works. Looks like it's something from either newer kernels or newer DTB. I fetched the DTBs from FriendlyArm own tree (https://github.com/friendlyarm/kernel-rockchip) but compiled into the Rockchip Kernel (https://github.com/rockchip-linux/kernel). \
