First, why are you not using file but whole partition?

With file you do not need to use -s.

(See man page, read is exhausting for key, so
it tries use the while device.)

-s takes size in bits (multiple of 8 bits only), so 1216.

Isn't there \n in the end of passphrase? The same syntax
for luksOpen should work for luksResume.

See man page "notes on password processing".

(Also check --debug output, maybe there is some more info.)
