Well spotted, but this does not explain the results of run CI_DRM_2670:

 21.60 igt at gem_exec_flush@basic-batch-kernel-default-wb
 19.84 igt at gem_exec_flush@basic-batch-kernel-default-uc

Yet, idle injection was active during the execution of these tests:
https://intel-gfx-ci.01.org/CI/CI_DRM_2670/fi-snb-2520m/dmesg-during.log

But anyway, I guess we need to check if this machine is not overheating or
otherwise consuming too much power (as reported by RAPL).
