First, from the cryptsetup log # Userspace crypto wrapper cannot use gost-xts-plain64 (-2). it seems that there is some problem with loading of your gost cipher implementation. What key size you are using in cryptsetup (default is probably 256bit)? LRW and XTS modes requires *two* keys in fact (tweaking+encryption). GOST should use 256bit key, so if you add --key-size 512 to your cryptsetup command does it help?
