all right. where does this driver-policy file come from? it sets
MODULES=dep, and thus overwrites MODULES=most from initramfs.conf. maybe
that's the problem?

why did you add the modules in the first place? did you already try to
remove them from the file again?

ok, substitute lsmod with 'cat /proc/modules' then, and give it a try
again.

so the bug is in no way related to cryptsetup. the keyboard doesn't work
in your initramfs at all. i strongly believe that modules are missing
from initramfs or aren't loaded.

don't know. maybe some of the modules do conflict, or they're
blacklisted, or not loaded for some other reason. i suggest to undo all
the changes you did to initramfs configuration and regenerate the
initramfs afterwards.

let's see. unfortunately i'm busy with other things at the moment, and
only have limited time to help you with debugging an issue that's not
even related to the cryptsetup package at all. but let's see ...

greetings,
