Description
Created attachment 139429 GPU crash dump
I get GPU hangs on Sky Lake integrated graphics when not booting with either:
i915.modeset=0 or video=vesafb:off
The hardware is a Dell 7040 with Intel i7-6700 CPU.
Xorg does not crash, but everything except the cursor locks up each time the GPU resets. Here his the drm message:
[ 41.823218] [drm] GPU HANG: ecode 9:0:0x859ffffb, in Xorg [2092], reason: hang on rcs0, action: reset [ 41.823219] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 41.823220] [drm] Please file a new bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 41.823220] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 41.823220] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [ 41.823221] [drm] GPU crash dump saved to /sys/class/drm/card0/error
Subsequent to this there are frequent repeated resets:

Kernel: 4.17.0 Xorg server: 1.19.6 Intel driver: 2.99.917+git20171229-1 Mesa: 18.0.0 GuC firmware: i915/skl_guc_ver9_33.bin HuC firmware: i915/skl_huc_ver01_07_1398.bin
I started out with a stock Ubuntu Xenial and progressively upgraded bits with no avail. Turning off modeset/vesafb was an acceptable solution until I needed dual display support.
