<pre>And hopefully swept back under the carpet with,
commit d2eeaf2bc04941444bfd52285b6183d6c84c262c (HEAD -> drm-intel-next-queued,
drm-intel/drm-intel-next-queued)

drm/i915/selftests: Disable preemption while setting up fence-timers
The impossible happens and a future fence expired while we were still
initialising. The probable cause is that the test was preempted and we
lost our scheduler cpu slice. Disable preemption during this test to
rule out preemption as a source of timer disruption.
