Cannot use OpenWrt Kmod

It seems that it is not possible to use openwrt kmod when building via buildroot.
Any single config change like selecting for a particular router will result in an incompatible kmod.
If force depends is enabled the kernel will crash and reboot.
This is probably due to the kernel stack smashing protection in the openwrt config not so much because of a binary incompatibility.
One of openwrt advantage is to be able to install modules from repository is there a way to fix this?

All your kernel modules need to be built at the same time as the kernel. They can then be later loaded from a repo, for that specific kernel.


The thing is we want to be able to use Openwrt's kmod without having to use openwrt default image or build our own custom kmod.
Before SSP this was possible.
