NanoPi M1 Plus Image using modern Kernel that breaks ethernet #6974
Description
> 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:

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/bootdirectory contents it gives:
- edge kernel (5.14.8) does not work
- current kernel (5.10.60) does not work
- 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 ?
