Hello Milan, I have checked again and I can now confirm that the problem happens only when using LVM version 2.2.02.148. After upgrading to LVM version 2.2.02.149 the problem disappears. However, it might not depend on the udev rule, as such rule had not been uninstalled when using LVM version 2.2.02.148. Also, I still cannot explain the reason why cryptsetup < 1.7.0 works fine even when LVM2.2.02.148 and the mentioned udev rule are installed.
