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.

Kernel dmesg from before the crash attached.
I also tried with Linux kernel 3.9.2 and there the system crashes hard aswell.
