See https://bugs.freedesktop.org/show_bug.cgi?id=98384 for more information
about my setup (but feel free to ask if you need any information obviously).

Every time nouveau gets loaded on this system, there is this line printed
(either in red in the middle of all other nouveau related ones in dmesg, or
alone on the console when modprobing manually):
nouveau 0000:01:00.0: priv: HUB0: 614900 00800000 (1d408200)

It is exactly the same line each time.
