I discovered a faitly simple way to have my system rebooted. I am
planning to solve it, but if anyone else alreday did that, please let
him/her say so.
I don't know if this only happens at my machine, but i dont think so. However
if you have the same problem, could you please give me an email?

The problem:
just logon on the console using sh or csh. press a few keys followed 
by a tab.  e.g: $ bras<tab>
and now hit the backspace several times, untill you "hit" the prompt.
If you press it again, you see some dirty characters appearing, most
of the time followed by a trap and a reboot.
I think the failure is inside pccons.c that seems to generate a ctrl-R
when it is unnecessary.
