Hello,
Lenovo T430 laptop with intel+nvidia hybrid graphics, optimus 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.
