I tried running supertuxkart on my MCP79 (9400M), got some artefacts, but it
did not freeze; the only error I got was “nouveau 0000:03:00.0: fifo:
CACHE_ERROR - ch 1 [DRM] subc 0 mthd 0060 data 80000002”.
Which version of Mesa, xf86-video-nouveau (or modesetting) did you have in
those tests?
For reference, I have:
Linux: 4.15.4
Mesa: 17.3.5
xf86-video-nouveau: 1.0.15
xorg-server: some 1.19.6 snapshot</pre>
