As written before, If I kick out the "stty intr '^C'" from root's .bashrc, then the second su succeeds. Running the stty command manually in this new shell is no problem. Can you reproduce this problem? It doesn't need XWindow or any special user. Simply login as root on tty2, and run "su". If it gets stuck, then you could login on tty3 and kill -9 ### the blocking stty.
