Steps:
------
1. Execute command:
cd <...>/intel-gpu-tools/scripts/
./run-tests.sh -r <path>/results -x .*suspend.* -x
gem_userptr_blits@swapping.* -x gem_dummy_reloc_loop -x gem_concurrent_all.* -x
gem_evict_everything@swapping-hang -x gem_close_race -x gem_cpu_reloc -x
gem_ctx_thrash.* -x drv_hangman.* -x drv_missed_irq_hang -x kms_setmode.* -x
gem_fence_thrash@bo-write-verify-threaded-y -x gem_multi_bsd_sync_loop -x
gem_reloc_vs_gpu@forked-interruptible-faulting-reloc-thrashing -x
gem_seqno_wrap -x
gem_userptr_blits@forked-sync-swapping-multifd-mempressure-interruptible -x

-x gem_pwrite@big-cpu -x gem_pwrite@big-gtt -x gem_pwrite@huge-cpu
2. Wait a moment
Actual result:
--------------
2. A lot of tests are failing. Log shows a GPU hang and Failed to reset chip
Expected result:
----------------
2. No GPU hang</pre>
