Are you able to unlock manually using cryptsetup(8) from that SSH session? If not, please share the output using the --debug flag. It might be that a module is missing, or perhaps on the newer kernel the block device holding hasn't shown up yet for some reason? See https://cryptsetup-team.pages.debian.net/cryptsetup/README.debug.html to debug the boot script and see what it's doing instead of launching askpass. (You should be able to get a shell in the premount stage via SSH too, but need to set the `break=premount` boot option first.) Hope that helps :-) -- Guilhem.
