--- Comment #3 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Sorry, all the hangs have happened with drm-tip v4.20-rc versions, not v4.19.

Last night there were again recoverable hangs on SKL, with drm-tip v4.20-rc4:
* GfxBench v5-GOLD2 Aztec Ruins GL & Vulkan ("normal") versions
* Ungine Heaven v4.0
* SynMark v7 CSCloth

Heaven doesn't use compute shaders, so maybe the issue isn't compute related
after all.
