Xorg.log

Hello, I get a freeze, I'm able to move the mouse cursor but nothing else.

I'm able to access via ssh and get the Xorg.log. I enabled the debug to have a more valid backtrace.

Feel free to ask whatever you need.

When the problem happens, In dmesg there is the following messages:

[11449.585126] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
[11449.585132] nouveau 0000:01:00.0: fifo: sw engine fault on channel 2, recovering...
[11451.584882] nouveau 0000:01:00.0: fifo: runlist 0 update timeout
[11453.880225] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]

bug 72180 seems to mention the same message error, but that bug was resolved as INVALID
I didn't read all comments, but the last comment seems to indicate that the problem is fixed in 4.1.
I'm using 4.4 and it is not fixed here.
