Description of problem: My system seems to be producing this oops about once every 2 seconds, continuously. I have not yet noticed any ill-effects from it. I have no idea what is triggering it. I have 2 monitors connected to my system, both via displayport interfaces. The laptop screen is closed and not in use. The system is a Lenovo W541 which I understand has some weird arrangement of both intel and nVidia graphics. To the best of my knowledge I am using the intel graphics exclusively. I am prepared to be wrong on the details of the graphics in this laptop.

I have the same issue and can confirm. To work around this: * Boot using UEFI (disable legacy boot in bios) * At the grub menu hit 'e' on the first line, and add the following to the end of the bootup line (should contain 'quiet'): nouveau.modeset=0 nouveau.runpm=0 Now everything will work as expected. Once you install, you will want to install the Nvidia proprietary drivers or otherwise edit /etc/defaults/grub to make sure those Nouveau parameters get set each boot
