Created attachment 135684 [details] Contents of /sys/class/drm/card0/error I was playing a Video inside a GNOME/Wayland session using vlc (as XWayland client, not with wayland Qt backend). The video did stutter very much and gnome-shell was nearly frozen, i.e. input was delayed by several seconds. Finally, VLC crashed and gnome-shell and XWayland were back to normal. I had a look in the logs (will attach syslog later) and there I found the GPU HANG.

Maybe a duplicate of bug #103502?
That error state appears incomplete. Please attach the original?
(In reply to Chris Wilson from comment #4) > That error state appears incomplete. Please attach the original? Sorry, that is the original. I got it from "cat /sys/class/drm/card0/error".
The problem is that error state is missing the batch contents, contexts, rings, status pages, without which we cannot triage the hang.
*** Bug 104901 has been marked as a duplicate of this bug. ***
I can reproduce this also with VLC, is there something I can do to get this fixed?
I looks like the error state is not retrieving the ring's batchs. A dmesg with debug information may help, parameters drm.debug=0x1e log_bug_len=2M(or bigger if needed) in grub.

Reasonable presumption that the error states are for the same bug.
Hello everyone, could you try mesa 18 and share results? Thank you.
Works fine now, I cannot reproduce the issue any more. xorg-x11-server-Xwayland-1.19.6-8.fc28.x86_64 libwayland-client-1.15.0-1.fc28.x86_64 libdrm-2.4.92-1.fc28.x86_64 mesa-dri-drivers-18.0.2-1.fc28.x86_64 xorg-x11-drv-intel-2.99.917-32.20171025.fc28.x86_64 kernel-4.16.9-300.fc28.x86_64 gnome-shell-3.28.2-1.fc28.x86_64 mutter-3.28.2-1.fc28.x86_64 mesa-libGL-18.0.2-1.fc28.x86_64
