Actually, it still happens without device-mapper, so I'm at the wrong place here. Sorry for that. I did some more tests with different distros and releases (Ubuntu 10.10 and 11.04alpha1, OpenSuse 11.3, Fedora 14), and almost all showed this behaviour; only OpenSuse immediatley set the device to read-only on the first write attempt, Ubuntu 11.04alpha1 crashed, but this may be because of the alpha status. Still not quite what one would expect, though. I will continue looking for help, can you point me in some direction? 'losetup' is part of util-linux, but I doubt this has actually anything to do withit. The loopback device code itself is part of the kernel, right?
