Yeah, I'm aware of that. Problem is that the loop starts when I try to log
in over SSH. I do get the welcome message, but I never get a prompt. And
as soon as the loop starts, the system is completely unresponsive. Even a
shutdown triggered from the system console does nothing. Only thing I can
do is a hard "poweroff".
