[Nouveau] PGRAPH - DATA_ERROR SEMANTIC_COLOR_BACK_OVER_LIMIT
Hi, I am not sure if this is an application bug or something nouveau-related. I have been attempting to play FlightGear but after a few minutes each time I start the game, my computer becomes completely unresponsive. Mouse movement sometimes works for a few seconds at a time, but no clicks work, nor any keyboard input (other than SysRq key sequences). Once I reboot, I can see in my log the following messages repeated again and again: [ 2440.151477] [drm] nouveau 0000:01:00.0: PGRAPH - DATA_ERROR SEMANTIC_COLOR_BACK_OVER_LIMIT [ 2440.151484] [drm] nouveau 0000:01:00.0: PGRAPH - DATA_ERROR [ 2440.151489] [drm] nouveau 0000:01:00.0: PGRAPH - ch 4 (0x00058f3000) subc 5 class 0x8297 mthd 0x0d78 data 0x00000002 Interspersed once in a while is: [ 2443.177390] nouveau_ratelimit: 1291 callbacks suppressed Is this an error with the application? I can report it to them if that is the best thing to do. Alternatively, if it is a sign of a nouveau issue, what information would you need to be able to track it down?
