So what is the > problem? What version of loop-AES are you using? What kernel version? File backed or device backed loop? What is the size of loop device? If I have make a wild guess about your problem, my guess is that you have managed to compile the driver for kernel configuration that does not match your running kernel configuration. > Another thing is after I comment out the aes_encrypt() > and aes_decrypt() that means loop-aes without > encryption everything is OK.
