This is the first time I see this behavior when adding support in the kernel config, it’s strange that you’re not getting any error when bitbaking the image. Have you tried to do this on the previous images?
Also, I was checking a thread where a user had some issues when loading signed kernel modules, and one of his replies said this:
“Just thought I would let you know that a colleague helped me resolve the issue.
Apparently, the yocto process compiles and creates the signed kernel modules and places them into a modules.tar.gz. However, during the flashall.sh process the signing and keys are stripped (don't know why). The solution was to overwrite (or add separately) the existing /lib/modules with the signed modules in the modules.tar.gz. If this is of interest to anyone, I can write another response and include more detailed information, but that is the general idea.”
This is the thread, https://communities.intel.com/thread/99136. This might not be your case, but you might find some useful tips or information in there.
