Hi there I have come across a problem with linux-crypto and I thought I'd ask if the problem exists for others as well. So here we go: modprobe cipher-aes dd if=/dev/urandom of=/tmp/test bs=1M count=1 losetup -e aes /dev/loop0 /tmp/test mke2fs -b 2048 /dev/loop0 mount /dev/loop0 /mnt If this fails for you -- that's the problem. I know how to work around it, I think I know pretty well what is going wrong internally, and I am currently working on a proper solution. My solution involves changes to the kernel, to losetup, _and_ the e2fsprogs, so if somebody knows a more simple fix -- please let me know. Otherwise, I'd like to hear if others are experiencing this behavior and consider this a problem, too.
