dmesg Linux 3.8.11 nouveau optimus before the kernel crash

I'm using Lenovo T430 laptop with intel+nvidia hybrid graphics, optimus is
enabled in BIOS:

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro NVS 5400M]
(rev a1)

$ uname -a
Linux localhost.localdomain 3.8.11-200.fc18.x86_64 #1 SMP Wed May 1 19:44:27
UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

I boot up the system with only laptop internal LVDS active on intel gpu, and
when in X session, I enable the second display on nouveau gpu connected to the
dock DP2/DVI connector. 
At this point the kernel crashes immediately.
