Rightio.  (I found that the failure is logged in the "do_rootfs" recipe,
but concentrating on the kernel recipe):

I found a problem, straight away:  The kernel recipe includes in its
SRC_URI a file that (looks like) it sets kernel configuration to load the
iwlwifi modules.
However when I build it and boot it and examine /proc/config.gz none of the
configuration from the kernel recipe are there

Grepping around for the configuration options I found this file in my build
section:
build/tmp/work-shared/apalis-imx8/kernel-source/.kernel-meta/cfg/merge_config_build.log
It is not updated on each build, but has been updated today, so I am unsure
on when and how it was created.

It says (in part)
