For what it's worth, I don't get these messages anymore since I replaced my CPU fan.
My graphics card has passive cooling only, and relies on air flow in the case, so CPU and case fans. The CPU fan was dead, had probably been for a long time. I replaced it and have not seen this issue ever since. Of course it probably is something else, but you could try and monitor temperature, just in case. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863390 Title: GPU lockup ring 0 stalled for more than X msec To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1863390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
