Hi, I recently set up a 2GB loopback encrypted filesystem on my 7.1 installation and everything went just fine following the HOWTO. I initialized the encrypted file with /dev/urandom, used losetup to initialize the file (using XOR for now, for testing/experimentation, probably twofish later), and set up /etc/fstab to automount the encrypted partition on boot. All in all everything works fine, except that when I try to do large file copies, such as e.g. moving 1+GB of data over to the encrypted partition, I get random lockups of my entire machine. No OOPS, no kernel panics, nothing. Just solid lockup requiring a hard reboot. I've looked at all the log files that might be relevant, but cannot see anything indicative of the problem. My config is: Sony Vaio PCG-C1VN (with Crusoe processor) SuSE 7.1 with 2.4 stock kernel 175 MB RAM, no swap partition Any help would be very much appreciated.
