Hello, I get these Oopses from time to time, but unfortunately(?) not often enough to be anywhere near reproducible. But they seem to be related to whatever activites my laptop/X-server/driver/gpu/screen is doing while I'm not present. The oops happens when I'm away for a while. So I guess it might be something related to screensaver and/or power saving actions. There is always a GPU HANG prior to the Oops, so these events are probably related. <6>[ 3925.798843] [drm] GPU HANG: ecode 9:0:0xfffffffe, in Xorg [850], reason: Hang on render ring, action: reset
