Hello Andrzej, Any special reason to stay with 16.04? Do you have any steps to trigger the hang again? If possible could you try with a newer kernel version, 4.13 or up? Could you please try Xorg 1.19 and Mesa 17.3? Thank you. It's a work computer, I'm staying with 16.04 because "it works" and updating usually introduces unnecessary problems. Anyway, this bug has occurred only once. I doubt that I would have any luck attempting to reproduce it. I have one guess - could this "Ring hung" be simply a result of the GPU having a large workload spike? I haven't verified this, but the app that I was testing could have tried to render an excessive amount of geometry during one frame. |

Created attachment 136079 [details] data from /sys/class/drm/card0/error I was testing a qt-based app. The UI froze for several seconds, then resumed without an issue. In dmesg, I've found the following: [958940.926878] [drm] stuck on render ring [958940.927417] [drm] GPU HANG: ecode 7:0:0x87dd7d10, in app [17354], reason: Ring hung, action: reset [958940.927418] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
