Okay, it turns out that Devuan Jessie includes two extra modules that
needed to be added to the Devuan Ascii /etc/initramfs-tools/modules file.

I'm not sure exactly when those two modules become necessary (to add
to the modules file), but until they were added the only way I could
successfully get a working boot was via the rescue method using the
older Devuan Jessie USB stick which always worked.

This is the modinfo for these two extra modules:
