dmesg for last good commit
I have a lenove thinkpad T61p with a NVIDIA Corporation G84GLM [Quadro FX
570M].
When connecting my external VGA monitor my monitor is no more detected
properly:
> cat /sys/class/drm/card0-VGA-1/status
gives now "disconnected"
Last good commit is
ef22c8bb7b3fac45919b7fde412d36d1a8367d51
drm/nv50/disp: call into core to handle dac/sor power state changes
First bad commit is
7ebb38b556485449bfaa506a196439f6a6fd6ebd
drm/nv50/disp: call into core for dac load detection
The responsible function is
nv50_dac_detect in drivers/gpu/drm/nouveau/nv50_dac.c (moved to
drivers/gpu/drm/nouveau/nv50_display.c in more recent kernels).
Also tried a 3.9.1 kernel. The problem still remains.
However, replacing nv50_dac_detect with the corresponding version from the last
good commit fixed the problem (tried a 3.8.10 kernel).

I seem to have much of the same problem.
I am running a Dell desktop with NVIDA Quadro NVS 295 graphic card and two
identical Dell monitors attache via DisplayPort.
I run Fedora 18 with all latest updates and using Nouveau drivers.
Starting with Kernel 3.8.11 it boots OK and both monitors works as expected.
Starting with Kernel 3.9.2, 3.9.3 or 3.9.4 boots and when trying to display
anything on monitor two it gets into problems.
It boots until its tries to start the Xorg server and then monitor 2 starts
flickering on and off. Monitor 1 stays with the boot logo of fedora.
Also during boot when booting I only have the boot logo of fedora on monitor 1
when running kernel 3.9.x while I have it on both screens when running kernel
3.8.11
I am able to hit CTRL+f2 to get a text login.
I will attache my dmesg output for both kernels.

I don't that this is related to this bug. Here the monitor stays blank as soon
as the nouveau driver is loaded.
