Black screen with nouveau in 3.8.x (regression)

2013-03-07 Thread Nick Bowler 
Hi folks,

Yesterday I upgraded one of my machines to 3.8.2 from 3.6.6.  This
machine has an old NV36 AGP board.  With the new kernel, as soon as
nouveau takes over the console the display connected via DVI goes dark
(the monitor goes into standby mode).  The display connected via VGA
continues to work fine.

Starting Xorg does not correct the problem.  Nouveau seems to know
that the display is connected:

  % cat /sys/class/drm/card0-DVI-I-1/status
  connected

I don't see anything unusual in the log either (full log attached):
