<pre>The dmesg from drmtip goes on for 300+s after the gpu hang, with no indication
of subsequent GPU malaise. As you have netconsole setup one thing you can try
is config DRM_I915_DEBUG_GEM to see if any sanity checks fails; make sure you
also have reboot on panic set.
As to a possible cause, could you try with intel_iommu=igfx_off</pre>
