test_enable_race() is a perf_pmu subtest ('tests/perf_pmu.c') that is trying to enable the PMU while under heavy (irq) engine load. Unfortunately the logs only show that the test started and then hangs so it is not obvious where the hang occurs. I might be useful to instrument the test to see if the hang occurs when loading the engine with gem_execbuf() or if it's a result of enabling the PMU under that load. Setting to CRITICAL as worst case would be that heavy load brings causes a hang.
