I agree, the kernel/HW is broken.

However, this fix is not necessarily wrong, as in, the real kernel 
fix/workaround may actually be worse than the problem it is trying to 
fix, because it would increase the power usage while only fixing a use 
case that has not been seen in the wild (or has it?).

We thus need to prove that this is the case and document this issue 
extensively in both IGT and the kernel. Until then, let's merge the 
revert to keep it in the task list:
