Bug Description
nouveau fills /var/log/kern.log and /var/log/syslog with _very_ frequent messages when the molecule xscreensaver is running.
This is a big problem as it prevents me from letting my machine do anything overnight (with the screenlock on).
I haven't tested other screensavers and don't appear to get messages otherwise. Here is an excerpt:

Both log files are actually 99GiB (they'd be bigger, but at that point my / partition was full). Both files contain almost 975M lines each (which is quite a lot for a file that gets rotated daily!)
I run a minimal system (log in to the console, start i3 with startx) and I have a keybinding to launch a xscreensaver (specifically the molecule screensaver from xscreensaver-
I had no problem under Ubuntu 15.04 32 bits, but for work-related reasons, I had to downgrade to 14.04 (64 bits).
