Sorry about that. Specifically I think you need these three patches: https://github.com/skeggsb/nouveau/commit/46ae630592a9082eea0ba513f588faac1014b7ab https://github.com/skeggsb/nouveau/commit/56bd00148306b14ae7b7d683c755992f47539fcc https://github.com/skeggsb/nouveau/commit/0fbb2f642a1714626c945ec14c892dbf64bb4f22 The first of those you already have. I'm fairly certain that the second patch will fix the "fifo: read fault" errors. I'm curious, though, how you manage to X to get the GPU involved at all on a Jetson TX2. Are you setting up DRI_PRIME? Or using Mesa patches to enable a "renderonly" setup? Thanks, Thierry
