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 , 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 df6b320a
Second one on SKL GT4e: 2017-10-04 844ae722
Only one on SKL GT2: 2017-10-18 f37af5ec
