--- Comment #8 from Tvrtko Ursulin <tvrtko.ursulin at linux.intel.com> ---
Reverting 6aef660370a9c246956ba6d01eebd8063c4214cb forces the decoupling mmio
usage until someone explicitly grabs the forcewake after reset. But that is
actually done on the first cmd submission which the test does do (wait_gpu).

So I still don't understand why this commit would be making a difference. Could
you put a sleep(5) at the end of the wait_gpu helper (igt) and see if that
makes any difference with 6aef660370a9c246956ba6d01eebd8063c4214cb both present
and reverted?

Another interesting fact is that gem_workarounds/basic-read always fails on BXT
on the OTC CI farm. Which makes me think the issue really isn't about the above
commit but some timing issue or and issue with decoupled mmio.
