System log file of 7 BUGs in nouveau

Problem description:
--------------------
GUI freezes. No user interaction (mouse, keyboard) possible. Only hard shutdown
possible.

System specifications:
----------------------
- Operating System: Ubuntu 15.04.
- Computer-Hardware: Acer Aspire 7520p
- Graphic-Card: Nvidia 7000m

Steps to reproduce:
-------------------
1. Start Ubuntu and log in
2. wait or accelerate the freeze by
2.1. starting firefox
2.2. starting a terminal

Why it looks like a nouveau bug?
--------------------------------
Well, I see something like the following in /var/log/systemlog each time, when
the GUI freezes. (I compared the seconds of the clock with the log-entries and
they match - always)

============================================================================
For more examples please look into the attached file (namely 'syslog_1').

I think I don't have to explain that the system is pretty unusable, because the
freeze happens about 1-5 minutes after the log in.

If you need any help or have questions - please ask :)

Best regards
Jedet
