Starting at CI_DRM_3422 and all following runs, so far up until CI_DRM_3425

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3422/fi-ctg-p8600/igt@gem_ringfill@basic-default-hang.html

dmesg-warn:
[  314.726587] i915 0000:00:02.0: Resetting chip after gpu hang
[  317.742384] [drm:i915_reset [i915]] *ERROR* Failed to reset chip: -110

the due to:
IGT-Version: 1.20-gac6739bc (x86_64) (Linux: 4.15.0-rc1-CI-CI_DRM_3425+ x86_64)
Test requirement not met in function igt_require_gem, file
ioctl_wrappers.c:1427:
Test requirement: err == 0
Unresponsive i915/GEM device
Last errno: 5, Input/output error
Subtest basic-all: SKIP

the following gem tests are skipped:
igt at gem_sync@basic-all
igt at gem_sync@basic-each
igt at gem_sync@basic-many-each
igt at gem_sync@basic-store-all
igt at gem_sync@basic-store-each
igt at gem_tiled_blits@basic
igt at gem_tiled_fence_blits@basic

some kms test pass, but then skipping due to the same reason as above for:
igt at kms_busy@basic-flip-a
igt at kms_busy@basic-flip-b
igt at kms_cursor_legacy@basic-busy-flip-before-cursor-legacy

then fail on:

the on one run so far there is a Softdog incomplete on:
