Can you try running lsinitramfs <initrd> | sort on each, and
compare what's included, to see whether that differs. (Using
lsinitramfs -l would need options adding to sort, and some
post-processing, to get much sense out of a diff.)
I have a system that's not fully configured, and is rather old.

However, they'll both be MODULES=most; perhaps I'll boot it sometime
and regenerate them with MODULES=dep.
Currently, this same machine, also MODULES=most, has:
