Would it be possible to apply 58586680ffad "drm/i915: Disable atomics in L3 for gen9" to stable kernels? I'm finding it quite easy to crash my Thinkpad X1 Carbon 6th gen with Blender on Fedora 34 (which is using the 5.11.y kernels). It applies cleanly, and I've been running 5.11.16 with the patch applied and seeing no obvious ill effects. --b.
