Hi, this is a bit confusing. Are you trying to rebuild a kernel using the linux- source-4.9 package with a custom config, or are you trying to rebuild the src:linux package with no change at all? If the former, could you provide the configuration you use? Can you also check if upstream just-released 4.9.75 builds with that .config? Regards, -- Yves-Alexis
