Yes, booting a small system with udev works! qemu in graphical mode boots up to the login prompt. But unfortunately each character i tried to type in is corrupt. Hence, its not possible to log in. In console mode getty causes a kernel oops. But it works now much better than before. Many thanks! regards, Jörg INIT: version 2.86 booting Mounting a tmpfs over /dev...done.
