Created attachment 139226 [details] errors logged by the kernel Occasionally when using the Chromium browser, X will freeze. This is accompanied by various errors in the kernel log (see attachment). I can reliably reproduce this by opening the following websites in Chromium: * https://www.youtube.com/ * http://www.ardmediathek.de/tv * https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Tutorial/Lighting_in_WebGL This is with X server 1.19.6 and xf86-video-nouveau 1.0.15. I originally saw this with Linux v4.16 and then reverted back to v4.14.35 LTS which didn't seem to exhibit the same problems at first. Also, with v4.16 the freezes seem to be more extensive, often requiring a reboot. With v4.14.35 the freezes are temporary and often even non-existent despite the errors logged by the kernel.
This [1] patch prevents random xserver freezes tested: GPU GTX 550Ti mesa 18.1.0rc2 xorg-server 1.19.99.905 xf86-video-nouveau-git 1.0.15.r5.gac8f7b9 DRI3 enabled I noted the same behavior with: mesa 18.0.1-1 xorg-server 1.19.6+13+gd0d1a694f-2 xf86-video-nouveau-git 1.0.15.r5.gac8f7b9 DRI3 enabled [1] https://patchwork.freedesktop.org/series/41258/ (rev 4) I'm not sure if it is related, but it's worth mentioning
