I found the following kernel patch in the comments of the freedesktop ticket :
https://bugs.freedesktop.org/attachment.cgi?id=106085 I can no longer produce the crash of my GPU with this patch. It has the same effect as these two commands as root : echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level echo performance > /sys/class/drm/card0/device/power_dpm_state In my case, it seems to have worked-around the issues I am having with the radeon driver. ** Attachment added: "Patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1508944/+attachment/4513894/+files/attachment.cgi.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1508944 Title: 1002:9591 ring 0 stalled for more than 10100msec To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1508944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
