Now it works fine for files but not for Devices: losetup /dev/loop0 /dev/sr1 losetup /dev/loop1 /dev/loop0 dd if=/dev/loop1 of=test.dat bs=2048 count=1024 Makes dd hang. (BTW: /dev/sr1 is a CD-ROM) Tried the same on /dev/hda1, /dev/sda1 with 2.4.2-ac7-your_patch and with 2.4.2-ac8. BTW: Did extensiv testing with and without the crypto patches. And all other tests worked fine! :-) -- Mario Hermann
