What kernel are you using ? This typically means that the kernel config
isn't correct.
If you aren't using linux-yocto, then the fragments we have in the layer
are likely
not being applied, and you'll need to manually configure your kernel with
the right
options.

Otherwise, it could be that the cgroups are not being mounted properly by
your
recipe, so have a look and confirm if cgroups or cgroups2 are in fact
mounted in
your image.
