I remember that fix was related to invalid virgl command stream found by afl, that would be able to loop millions of iterations in some code, such as vrend_renderer_resource_create(). I wonder if you could trace it back to some client code. Also worth if there is a valid opengl reproducer, that could be a new piglit test.
