No failures here. Many thanks for your efforts. An easy way to reproduce the problem might be to try Ubuntu 9.04 (Jaunty Jackalope) Alpha 6 available at: http://cdimage.ubuntu.com/releases/jaunty/alpha-6/ I've tried two Live versions without hard disk changes: Desktop CD http://cdimage.ubuntu.com/releases/jaunty/alpha-6/jaunty-desktop-i386.iso and Netbook Remix http://cdimage.ubuntu.com/releases/jaunty/alpha-6/jaunty-netbook-remix-i386.img On different machines (desktop PC, netbook, notebook) my test script fails within 40 iterations. > I dowloaded linux-source-2.6.28_2.6.28-11.36_all.deb from nearby .fi mirror > http://www.nic.funet.fi/pub/mirrors/archive.ubuntu.com/pool/main/l/linux/ > > md5sum: > 41d603022c136e37caac2b9f854d2dc6 linux-source-2.6.28_2.6.28-11.36_all.deb > dc8ef59b8e2133d72e874660dcad68bf linux-source-2.6.28.tar.bz2 > > What is/was the exact kernel source version number that you used and where > did you get it from? I recompiled my kernel lots of times with different kernel versions and different configurations. The one which worked for you dc8ef59b8e2133d72e874660dcad68bf linux-source-2.6.28.tar.bz2 as well as linux-source-2.6.28.8.tar.bz2 from kernel.org did not work for me. (See details below.) > Who compiled your kernel sources and loop-AES module? > And how? Show me the commands. 1. Install util-linux-ng-2.14.2 with util-linux-ng-2.14.2-20090214.diff (following README of loop-aes) 2. Install kernel Ubuntu package linux-source, version 2.6.28-11.36, contains /usr/src/linux-source-2.6.28.tar.bz2 with md5sum: dc8ef59b8e2133d72e874660dcad68bf linux-source-2.6.28.tar.bz2 Ubuntu package linux-headers-generic, version 2.6.28.11.13, contains /usr/src/linux-headers-2.6.28-11-generic/.config with md5sum: bd342efb2eb80cd8db38355ee24d3999 .config tar xjf linux-source-2.6.28.tar.bz2 cd linux-source-2.6.28 cp /usr/src/linux-headers-2.6.28-11-generic/.config . make menuconfig - deselect CONFIG_BLK_DEV_LOOP - change Reiserfs and Minix from =m to =y make as root: make install make modules_install 3.
