BDW GT3 error state (Mesa: 24fe4e6143)

GfxBench T-Rex offscreen tests is still GPU hanging.  Last error is from few
days ago:
-------------------------
i965: Failed to submit batchbuffer: Input/output error
...
[ 4052.788996] [drm] GPU HANG: ecode 8:0:0x84dfffc4, in testfw_app [2869],
reason: Hang on rcs0, action: reset
-------------------------

It happened both on BDW GT2 & GT3 with following Mesa version:
2017-10-21 24fe4e6143

See the attached error log.


Valley hasn't GPU hanged within last 2 months.  It segfaulted with Mesa:
2017-09-03 49b428470e

But that's the last problem I've seen with Valley, i.e. Valley part of this bug
isn't anymore reproducible.
