SKL GT3e error state (first hang)

In last 2 months there have been GPU hangs with Unigine Heaven v4.0 on SKL GT2,
GT3e & GT4e:
[ 1328.788039] [drm] GPU HANG: ecode 9:0:0x84df7ec4, in heaven_x64 [2197],
reason: Hang on rcs0, action: reset

Heaven settings are: quality = high, filtering = trilinear + 4x anitsotropic,
no AA, Vsync disabled, Tessellation enabled.

These GPU hangs happen both with 4.13 drm-tip kernel (from early September),
and latest drm-tip kernel, with both kernels, the hangs happen with the same
Mesa commits.

They don't happen on multiple machines with same commit, only on single
machine, and even then not on every run, so I think triggering of the hang is
very timing related.

First hang was on SKL GT3e:
2017-10-03 df6b320a83c89b6401fde888375529b3fc66f4fa

Second one on SKL GT4e:
2017-10-04 844ae722c4416420f961ce8a89b5e5278865376c

Only one on SKL GT2:
2017-10-18 f37af5ec8d351fe20e74b05059bea12236220e02

Latest ones happened two days in row on SKL GT4:
2017-11-01 8d8b9d11c97a679c0954a2f2e7ed8ddcd248ccfa
2017-11-02 a29869e8720b385d3692f6a74de2921412b2c8c1
