I'm doing some testing to check if I can use Armbian on my NanoPi M4. It seems pretty stable except for one problem with the ethernet. Basically after some data transferred, it dies.
This is an iperf3 log:

I've tried almost all kernels available for Armbian, Buster and Stretch as well. Same result.
With FriendlyCore instead, it seems working:
This is the kernel used by FriendlyCore:
Linux NanoPi-M4 4.4.167 #1 SMP Fri Jul 12 17:32:47 CST 2019 aarch64 aarch64 aarch64 GNU/Linux
Lowering the speed of the ethernet card to 100Mbs, it's "solving" the issue.
Does anyone have the same problem? I searched around the forum, but I didn't find anything.
It seems pretty similar to this: https://github.com/rockchip-linux/kernel/issues/27
