More probing. When I use type "reboot" via ssh. The machine will
able to exit the black screen  and show normal text based terminal
for the systemd shutdown message.

However, even if I switch the default run level to 3, without starting
X. The black screen still appear. I guess the black screen disappear
when kernel stop using virtual terminal.

I also verify that, in the good 3.6.x kernel. I am able to logout from
X and log back in without trigger black screen of death.
