The PCI device 0x10de087d (ION) at 02 at 00:00:0 has a kernel module claiming it.

[Aaron Plattner]

Check the output of "lsmod" for modules that can claim that device. 
It's probably either "nvidia" or "nouveau".  I think you can find out 
for sure by running

   readlink "/sys/bus/pci/devices/0000:02:00.0/driver"

Unload the conflicting driver and try again.
