Nope, no lockup without va (I may only be lucky though if the bug is there but only shown when using va).
That's indeed possible: Using virtual address space will catch out of bounds memory access that may otherwise go unnoticed.
So, I think in this report we should focus on the rendering regression(s), and track the lockups in other reports.
