Anywhere between 1-2 hours of running a driving simulation using a proprietary Qt5 based navigation application we're observing the attached GPU hang.
CPU: Intel(R) Atom(TM) CPU E3840 (Baytrail)
Other: Weston 1.0.6 (proprietary DRM rendering backend)
Mesa 13.0.6 (stock i965 driver from this)
The issue wasn't previously seen on our 4.4.x based released, however we were using a mesa 9.x based proprietary user-space driver, and a similar driver in the kernel (though it was essentially a wrapper around i915)
Unfortunately due to the version of Weston we're using we won't be able to easily upgrade mesa from 13.0.6 (it's a binary blob)

Ugh, it does look to be an unhappy mesa batch. I think you find yourself caught between a rock and a hard place.

Thanks for the quick reply, is there anything I could take a look at here (short of moving forward to mesa 18 and a newer weston)?
James, can you at least test with Mesa 17.2 and 18.0rc4, to see if either of those branches resolves your issue?
