kernel messages showing "link training failed"

Complete kernel messages showing "link training failed".

At 11:34 the console went blank and the monitor started to go into power save,
but I hit a key while it was still powered on showing a "Power save mode"
message, before it actually powered down. Nouveau said "training complete" and
I got the image back.

At 11:44 the monitor went into power save again and I let it power all the way
down. Nouveau says "link training failed" and then "training complete" but the
monitor just goes back to power save, there is no image.
