If I comment out the reference to loop in /etc/modules-load.d/modules.conf,
the error disappears. Other modules deem to load fine.
I cannot find any reference to the "loop" module??

root@argus-dev:~# find /lib -name loop*
root@argus-dev:~#
It's built-in:
CONFIG_BLK_DEV_LOOP=y

The original modules.conf file (which is a symlink to ../modules) is:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
loop
debian 'upstream' builds it as a module by default..

https://github.com/RobertCNelson/linux-dev/blob/master/patches/debian-armmp#L1577

we can change it to match...
So weird.. haven't tweaked the config but.. I just did:

./build_kernel.sh
./tools/install-kernel.sh

to verify it before the change..

That works as is..

Regards,

This is very strange. I just started from scratch with a fresh clone of 
linux-dev. I still get a failure as follows:
root@argus-dev:~# systemctl status systemd-modules-load.service
systemd-modules-load.service - Load Kernel Modules
          Loaded: loaded 
(/lib/systemd/system/systemd-modules-load.service; static)
          Active: failed (Result: exit-code) since Sat, 01 Jan 2000

loop

If I comment out the "loop" line as below - all works fine.

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
