Werner Posted April 26, 2020 Share Posted April 26, 2020 5.90 | arm64 | aarch64 | 5.1.0-aml-s905 Your Armbian seems way outdated. Try a up-to-date image on a different sd card or upgrade your kernel package at least. Link to comment Share on other sites More sharing options...
UniformBuffer Posted April 26, 2020 Share Posted April 26, 2020 I have a Le Potato sbc (s905x) and i have encountered the same bug. It has to do with the cma memory allocation used by the gpu that reserve memory, making it unavailable for the cpu. After reporting on this forum, some community members quickly found the problem and fix it. This bug should be already fixed with last kernels, you only need to update (now i have 5.4.28-meson64). Thanks again for the support! Link to comment Share on other sites More sharing options...
