Nope. The box is working properly: I checked it by logging via ssh and digging 
throoup list of processes and their states; the only data which can not get 
throudh is serial from G2 to serial console. I can (blindly) login, type `sleep 
50' and see sleep process from ssh connection. After logout, getty _sometimes_ 
returns sio0 to the proper state, so 'login:' is visible on the other side.

What is also interesting, that the box is _never_ in this state on 
boot phase or single user sh: only after getty/login, and not every time.

s/is/if/ of course. Try to disable getty in /etc/ttys, and start 
tip -9600 ttyd0 on G2 side - can you communicate with the other side?
