losetup -a blocks when loop is written to

Hi


When i do a 'losetup -a' while a manually setup encrypted loop is 'zero'ed with
dd if=/dev/zero of=/dev/loop<x> bs=4096 count=<y>
It blocks, just before the written to loop would be printed, until dd is finished, which may take several hours.

As even after 'KILL'ing the process it stays in the process list, i assume that something on the kernel-site is blocking.


Kernel: 2.6.20
Loop-aes 3.1e
Distro: Debian-SID, losetup from loop-aes-utils Package.

cryptic, powerful, unforgiving, dangerous.
