<pre>Looking at the error state for the i915.semaphore=1 i915.enable_ppgtt=0 case,
the hang there is is the MI_SEMAPHORE_SIGNAL code. I've put some fixes for gen8
semaphores at <a href="https://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=semaphores">https://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=semaphores</a>
Could you please see if they make the w/a i915.semaphore=1 i915.enable_ppgtt=0
case more stable?</pre>
