           Summary: GPU HANG: ecode 7:0:0x87f57ff8, in navigation

Card error

Anywhere between 1-2 hours of running a driving simulation using a proprietary
Qt5 based navigation application we're observing the attached GPU hang.

Kernel: 4.14.19
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)
