Hi, All: I port the xts-aes algorithm to FPGA board and use it to encrypt/decrypt the disc. i will get the bellow information But when excute the bellow commands cryptsetup luksFormat -c aes-xts-plain -s 256 /dev/loop0 or cryptsetup luksOpen /dev/loop0 test0 I get the bellow information .... device-mapper: remove ioctl failed: device or resource busy .... But others are all fine! I can format and mount test0. So i want to know why the message is printed? Thanks! Best REgards Bai Shuwei -- Love other people, as same as love yourself!
