NanoPi M1 Plus Image using modern Kernel that breaks ethernet

[InnovoMagicCube]

          > I now added the execute flag to 99-dietpi-uboot (via `chmod +x`) and did an `apt reinstall linux-image-edge-sunxi linux-dtb-edge-sunxi linux-u-boot-nanopim1plus-edge`. Now we have, what we expected:

Further step

Testing this with a reboot to the edge kernel 5.14.8 and prove the original LAN/WLAN issue. Tataa: The problem is back again, only LAN or WLAN can be activated, but not both in parallel:

The legacy kernel 5.4.88 shows the working condition:

Final testing

With these steps (apt remove ..., apt install ..., check for the /boot directory contents it gives:

• [ ] edge kernel (5.14.8) does not work
• [ ] current kernel (5.10.60) does not work
• [x] legacy kernel (5.4.88) works

Other kernels are not available:

root@DietPi:/boot# apt-cache search linux-image | grep sunxi
linux-image-current-sunxi - Linux kernel, version 5.10.60-sunxi
linux-image-edge-sunxi - Linux kernel, armbian version 5.14.8-sunxi edge
linux-image-legacy-sunxi - Linux kernel, version 5.4.88-sunxi
root@DietPi:/boot# 

Result

-->> I will generate images for Buster and Bullseye based on the legacy kernel.

This is an old issue and since it was closed, I used it to reopen a new issue. Hopefully this was the correct thing to do. I have a couple of these devices. I installed a new 9.2 dietpi image on the device which uses a later kernel and I am having the ethernet / wifi issue again. Is it possible to lock the M1Plus builds to kernel 5.4.88 as it is the only one that works for this device? Or if not, how do I roll back to t5.4.88 Kernel and prevent future dietpi updates from updating the Kernel ?

Any update on this issue :)

You should in the meantime have Linux 6.6, and there were much newer kernel versions which had no issues. Since you just pasted a 3 years old quote, could you instead fill the bug report template and add the exact errors/issues/symptoms you face on your system? And please add the following, to get an overview over the network interfaces:

ip l
ip a
ip r
