damsma,

Glad you've figured it out! This was a bug in the Debian build scripts in previous kernel. So when you upgrade the kernel to the latest, you won't need to do this anymore.

Updated 06 Oct 2019:

Kernel linux-5.3.2-kirkwood-tld-1 package has been uploaded. The following features were added/updated:

- This kernel is now configured to run with Kirkwood boxes up to 2GB RAM.
- Updated Dell Kace M300 DTS.
- This kernel header now can be installed and used to build cryptodev module, without any special tweaks.

damsma,

Not menuconfig.

cd to the source directory and run

make

Usually the kernel config changes overtime when I add/remove or move a loadable module to in-kernel module (so it always run during kernel start up), or move an in-kernel module back to loadable module (if it is something not popularly used).

So comparing an old kernel to a newer one, many versions removed, is not really good way to check something. You just either builld an out-of-tree module and see if you can. Or look for something with find command.
