Created attachment 118962 [details] Dmesg I have already reported this issue on lauchpad: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1487553. My Desktop freezes and Compiz process occupies 100% of CPU for a long while, if you wait 3-4 minutes it will recover, but the issue is very annoying. This is my hardware: https://gist.github.com/anonymous/3203c7c5a43a509c0f22. I have Ubuntu Wily Werewolf (development branch) 15.10 installed.
Does this happen without suspend/resume? If not, how is this different than bug #92522 which you filed earlier today?

Yes this happens without suspend/resume. While the other bug was a desktop freeze after resume from suspension, this happens using the desktop normally, it gets slow all of a sudden, freezes, I open terminal (CTRL+ALT+F1) and with the top command I can see compiz process using 100% of CPU. After like 3-4 minutes this process uses less CPU and desktop becomes usable again.
Do the set_domain messages in dmesg coincide with the freezes?
(In reply to Ilia Mirkin from comment #3) > Do the set_domain messages in dmesg coincide with the freezes? I will have to check this out, never noticed this before. I will check this the next time my desktop gets freezed and let you know.
Please give the patch at http://lists.freedesktop.org/archives/nouveau/2015-October/022732.html a shot -- it will hopefully help with the suspend/resume issues, and who knows -- perhaps even fix these -- you only have 256MB of vram, so similar situations will occur as with suspend/resume, with buffers getting swapped out.

Ok I will give it a shot and let you know. Meanwhile it has just happened again, I will attach two screenshots with top command and one with dmesg, just for you info.

I am waiting for Ubuntu to have the 4.3-rc7 kernel and install it: http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D so it will be easier for me to test your patch. I will let you know what happens. Thanks.

You reported in bug 92504 that the suspend/resume issue was gone... is this one as well?

I was waiting some time before answering to see if this issue occurred, but it hasn't occurred since I installed Ubuntu 4.3.0-040300rc7-generic kernel, so I can affirm that the issue is solved.
