Bug#956511: linux-image-5.5.0-1-amd64: general protection fault in i915_active_ref with 5.5
Hello maintainer,
I just stumbled across this as I get the same crash. To answer the question you posed the original reported, this happens to me without nvidia drivers loaded (I'm on a Lenovo X1 Carbon Gen 6 so it only has the one graphics card). The card I have reports as VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07).
My log file got cut when I force-restarted, but it looks fundamentally the same as the one you already have.
