kernel oops photo

Since debian testing kernel update from 3.16.2 to 3.16.5 (also reproduced with
3.16.7), I sometimes (~3/4) get a crash few seconds after lightdm launch.

It seems to be a reproduction of that (bisected) fedora bug:

--- Comment #1 from Pierre Moreau <pierre.morrow at free.fr> ---
Could you please retry with kernel version 3.19 (or later) as there was some
fixes related to fences and pci_ignore_hotplug that were merged?

Yes, sorry for the lack of follow-up. This has been fixed by a debian kernel
update somewhere in february.

Looking at the changelog, my guess would be by this commit:
    - nouveau: move the hotplug ignore to correct place. (regression in 3.16.4)

Merci
