Description Michal Suchánek 2017-05-04 19:42:33 UTC 
It seems this error has started since 4.10 or is much more frequent. I was able to run for days with 4.9 until different error triggered but with 4.10 I get these fence errors within a day locking up the GPU

Do you happen to use xf86-video-nouveau <= 1.0.13? If so, could you try using instead the modesetting DDX or xf86-video-nouveau >= 1.0.14? Nouveau switched to atomic modesetting in 4.10, revealing a bug in the Nouveau DDX which got patched in 1.0.14.
