I'm new to requesting stable patches, but I thought sending to the stable mailing lists would keep the proper folks in the loop. Sorry about that. The bug that the commit fixes has quite a long documentation trail: [BAT execlists] Sporadic - gem_exec_suspend basic-s4 GPU hang after resume https://bugs.freedesktop.org/show_bug.cgi?id=96526 I've had problems with that one and this one that is not fixed in 4.10.x stable: [Regression BDW] kernel panic in Intel i915 module, complete system freeze in 4.10-rc2 https://bugs.freedesktop.org/show_bug.cgi?id=99295 Thanks, Eric _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
