            Bug ID: 105304
           Summary: [BAT] [BSW only] igt at gem_sync@basic-each - GPU hung ->
                    wedged -> WARN_ON(intel_gpu_reset(i915, (~0)))
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium

Starting with GPU hang:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3852/fi-bsw-n3050/igt@gem_sync@basic-each.html

(gem_sync:3220) igt-aux-CRITICAL: Test assertion failure function sig_abort,
file igt_aux.c:481:
(gem_sync:3220) igt-aux-CRITICAL: Failed assertion: !"GPU hung"
Subtest basic-each failed.

Some skipped tests. 

Then first test getting that the machine is wedged:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3852/fi-bsw-n3050/igt@kms_pipe_crc_basic@hang-read-crc-pipe-c.html

(kms_pipe_crc_basic:3502) igt-gt-CRITICAL: Test assertion failure function
igt_force_gpu_reset, file igt_gt.c:407:
(kms_pipe_crc_basic:3502) igt-gt-CRITICAL: Failed assertion: !wedged
Subtest hang-read-crc-pipe-C failed.
