<pre>Сhris, I'm not sure I understand your position. Are you saying that it's a
normal state of affairs that userland can create a condition where via a series
of unprivileged library calls that go through i915 kernel driver, a machine can
be killed?
I dare say, that presents a wonderful exploit opportunity where an
appropriately crafted **unprivileged** userland code would kill any Linux
machine with an Intel GPU.</pre>
