netconsole log from nouveau before hang

Nouveau works fine on Dell Latitude C810 (GeForce2 Go) if no external monitor
is connected and also when an external monitor is connected but not enabled
before booting Linux.

However, when the external monitor is enabled (internal LCD is automatically
disabled - seems that the BIOS does not support clone mode), machine hangs
during nouveau initialization.

The weird thing is that when the monitors are switched using Fn+F8 before boot
(doesn't matter which one is kept enabled), nouveau does not hang.

The same thing happens with Debian Wheezy default 3.2 kernel and also 3.16
kernel from backports.
