This also looks like the bug documented under https://bugs.freedesktop.org/show_bug.cgi?id=92504 and https://bugs.freedesktop.org/show_bug.cgi?id=91125 . I think 939436 is also the same problem and have commented there. The 100% CPU usage is by plasmashell and I timed the freeze as being for 70, 80, 90, 220 and 280 seconds in various cases. While plasmashell is occupying one processor, the clock stops updating (mine shows seconds). Many applications still work and it is possible to minimise windows under these conditions. An open Konsole permits "top" - which shows plasmashell - or dmesg - which shows the following messages in my case.

Thanks for your bug report! Nouveau is an experimental driver under constant heavy development. This means that we cannot follow it closely, as we are not part of its team with reverse engineered knowledge of NVIDIA cards. In case you wish to stick with nouveau and to help us improve its support in openSUSE, you can try our latest kernel, Mesa, and xf86-video-nouveau packages: http://kernel.opensuse.org/ https://build.opensuse.org/package/show/X11:XOrg/Mesa https://build.opensuse.org/package/show/X11:XOrg/xf86-video-nouveau Testing the latest versions is a prerequisite in order to inform nouveau's upstream developers of any bugs you find: https://nouveau.freedesktop.org/wiki/Bugs/ Once you are aware of an upstream fix for your issue, please reopen the bug and let us know. We will be happy to include it in your openSUSE distribution if it's technically feasible. Alternatively, you can install NVIDIA's proprietary driver instead: https://en.opensuse.org/SDB:NVIDIA
