question: What will happen to buster when kernel 4.19 goes out of life in Dec2020?
See EOL for 4.19. https://www.kernel.org/category/releases.html If buster debian 10 has to change the kernel to 5 in Dec 2020, it will be untested. And it would be preferable to have kernel 5 before buster is realeased during the testing phase. Or will you do your own patchsets on an out of life 4.19 kernel? Regards Thierry
