[17204.959850] [drm] GPU HANG: ecode 7:0:0x85dffffc, in hl2_linux [5672], reason: Hang on render ring, action: reset
[17204.959851] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[17204.959851] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[17204.959852] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[17204.959852] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
