@userkhen, thank you very much! Indeed, updating to "stretch" and adding the given option makes everything works on a updated system.

Indeed, It is a DSA config. I can't really make many tests, because this SBC is the router been used on my house for everything. I have made the wifi hack, I desoldered the buggy original wifi card and soldered a nice and compatible one, and I have a sata HD that works, with no power problems even powering by usb. If somebody figures out how to change the configs to work on newer kernels, let me know.

I am not an expert, don't know for sure what is happening. When I update the kernel, everything seems to be working fine, the devices are recognized, but nothing works, like ppp connection and the switch. I guess there were a change in the switch driver on newer kernels? But I don't know what to change on my configs to make it work again...

I am using this: "Welcome to ARMBIAN 5.31 stable Debian GNU/Linux 8 (jessie) 4.14.84-sunxi". It works flawless, but I can't update the kernel because of the ethernet. Since I am not an expert, I don't know the issue, everything seems to be recognized on newer kernels but I can't make it work.

I know Lamobo-r1 has many problems and that the support ended, but it works fine for me. Everything works fine with kernel 4.14.84-sunxi, however, when I update the kernel, the b53 switch does not work anymore. I need to update the kernel to add another wifi usb dongle that seems to work only with newer kernels (https://github.com/aircrack-ng/rtl8812au/issues/272#issuecomment-467983704). Anybody experiencing the same problem? Any ideas for a workaround?

I can't make the b53 switch driver to work with newer kernels? Anybody had success? Works well for 4.14.84-sunxi, but does not work for the 4.19.x...

I changed from ubuntu to debian, and with the mainline kernel the wifi seems to work out of the box.
