So, I also tested 4.9.135-1 on a Bananapi board and can confirm it works. I would suspect the issue is caused by Debian's kernel configuration or changes. The Kernel CI project has ARM hardware, including the Bananapi board and does tests of stable kernel updates to verify that the kernel boots. At least with multi_v7_defconfig and sunxi_defconfig, upstream 4.9.144 does boot on Allwinner-based hardware, see: https://kernelci.org/soc/allwinner/job/stable-rc/kernel/v4.9.144/ On a sidenote: This issue makes me wonder if Debian's approach to kernel updates (i.e. not bumping the version number/ABI and overwriting the kernel image and modules) is really the best option. IMHO Ubuntu's handling of kernel updates is more robust. It would have made things much easier today if I could have simply selected an older kernel in the bootloader, rather than having to recover one from a backup. Kind regards, Timo
