Any progress on this issue?

If I issue shutdown command from an ssh session, the console is usable.
If I switch to ttyv1(alt+F2), login as root, then issue `shutdown now',
the screen locks up but I can switch to ttyv0(alt+F1) and it accepts
the keystroke.  An odd thing is that you can switch back to ttyv1 from
ttyv0 after going to single-user mode.
