commit 75d04a3773ecee617847de963ae4195d6aa74c28 ("drm/i915/gtt: Allocate va range only if vma is not bound")


<6>[  183.045461] [drm] stuck on render ring
<6>[  183.055187] [drm] GPU HANG: ecode 5:0:0xfaffffff, in kms_flip [2045], reason: Ring hung, action: reset
<6>[  183.065551] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
<6>[  183.077974] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
<6>[  183.087866] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
<6>[  183.098583] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
