[dm-devel] Problem with cryptsetup/device-mapper



Hello all, I am having some problems setting up a crypted device, and to me it seems to have with device mapper to do. I have loaded what modules I know is necessary as you can see below and I have tried different devices and pure files (ex /tmp/myimage which I created with dd if=/dev/urandom).

I am running Debian Unstable and I have tested it with 1-2 week old packages and fully upgraded. I also talked to google for an hour, be he wasnt very nice to me, found no valuable information at all.

Any help appreciated.
