kernel log with nouveau.debug=trace, v3.8-rc5-51-g4f84a11

TV does not receive signal when connected via HDMI to my Asus G50V laptop.
Laptop is single-GPU, NV96. xrandr shows HDMI as connected, having a mode, and
it should just work but doesn't. TV does not detect a signal.

LVDS works just fine.

I have tried:
- switching HDMI on and off via xrandr
- setting different video modes with xrandr for the HDMI
- booting with and without HDMI cable connected
- hotplugging HDMI

DDX 1.0.6.
Kernel is the nouveau kernel based on 3.8.0-rc5, v3.8-rc5-51-g4f84a11

    drm/nouveau/therm: reduce stack usage of nouveau_therm_ic_ctor


The nvidia proprietary drivers can run the TV via HDMI fine.

This is the first time I am trying to run nouveau with HDMI on this machine.

In the kernel log at timestamp 93, I was in X and ran:
$ xrandr --output LVDS-1 --auto --output HDMI-1 --auto --right-of LVDS-1
Before that X had seemed to set up a clone mode at the laptop panels resolution
also on TV.

#56601 - I have not even attempted audio yet, video only.
