--- Comment #6 from Eero Tamminen <eero.t.tamminen at intel.com> ---
With Mesa git head and few months old 4.13 drm-tip kernel:
* Last SKL GT2 & GT4e hang is from 2 weeks ago
* Several SKL GT4e hangs in November
* Hangs on SKL GT2 on mid-October & mid-December
* no hangs on SKL GT3e since start of November

With drm-tip kernel and few months old Mesa git:
* On SKL GT2, only visible hang after start of November is hang on mid-December
* No visible hangs on SKL GT3e / GT4e in past 3 months

With latest Mesa & drm-tip kernel git versions:
* No visible hangs since beginning of November

-> It seems this could be more kernel than Mesa related, and potentially fixed
there.

(Or timings have changed so that it doesn't appear with latest git versions.)
