As we ordinarily use a spinning batch to trigger a hang, we cannot do so without execbuf. On the other hand, if we do a manual reset of the wedged driver, we expect it to remain wedged and for the reset to fail; failing the test. Even if we remove the igt_assert(!wedged), the test is suspect as we don't know if the reset took place and so do not know if the conditions the test is trying to setup apply.
