Created attachment 144591 [details] BXT i915 error state Setup: * HW: BXT J4205, SKL GT2, KBL GT3e * OS: Ubuntu 18.04 * kernel: drm-tip compiled from git * GUI: Unity, using Mesa & Xorg compiled from git Test-case: 1. Run GfxBench (v5) Driver2 offscreen benchmarks: testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080 --fullscreen 1 --test_id gl_driver2_off 2. Run SynMark2 (v7) Batch5-7 tests $ for t in 5 6 7; do synmark2 -homeDir $PWD OglBatch$t; done Expected outcome: * No GPU hangs, performance of each test-run is about same Actual outcome: * Every 5-10th run there's recoverable GPU hang and clearly lower perf First time I saw this 15th of June. So the regression may have come between following drm-tip commits: * a0195925ba at 2019-06-14 16:19:08: drm-tip: 2019y-06m-14d-16h-18m-09s UTC integration manifest * 39e3d39be3 at 2019-06-15 15:21:37: drm-tip: 2019y-06m-15d-15h-20m-54s UTC integration manifest Notes: * These are odd tests to be GPU hanging, as GPU functionality-wise they're simple and more CPU than GPU bound

In addition to these devices, I have only BDW on which this isn't visible, so the issue seems GEN9(+) specific. It might happen also on newer platforms.
