While looking for some improvements on cpu-on-off-test.sh, I investigated the path that is taken on azure. One good tool to debug these failures is the cpuhp tracing. echo 1 > /sys/kernel/debug/tracing/events/cpuhp/enable echo 1 > /sys/kernel/debug/tracing/tracing_on cat /sys/kernel/debug/tracing/trace_pipe & echo 0 > /sys/devices/system/cpu/cpu1/online bash-2660[001] 10306.404476: cpuhp_enter: cpu: 0001 target: 143 step: 213 (cpuhp_kick_ap_work) cpuhp/1-14 [001] 10306.404506: cpuhp_enter: cpu: 0001 target: 143 step: 212 (sched_cpu_deactivate) cpuhp/1-14 [001] 10306.420476: cpuhp_exit: cpu: 0001 state: 211 step: 212 ret: 0 cpuhp/1-14 [001] 10306.420502: cpuhp_enter: cpu: 0001 target: 143 step: 189 (msr_device_destroy [msr]) cpuhp/1-14 [001] 10306.420623: cpuhp_exit: cpu: 0001 state: 188 step: 189 ret: 0 cpuhp/1-14 [001] 10306.420629: cpuhp_enter: cpu: 0001 target: 143 step: 187 (mce_cpu_pre_down) cpuhp/1-14 [001] 10306.420653: cpuhp_exit: cpu: 0001 state: 186 step: 187 ret: 0 cpuhp/1-14 [001] 10306.420654: cpuhp_enter: cpu: 0001 target: 143 step: 184 (hv_synic_cleanup) cpuhp/1-14 [001] 10306.420655: cpuhp_exit: cpu: 0001 state: 183 step: 184 ret: -16 cpuhp/1-14 [001] 10306.426523: cpuhp_enter: cpu: 0001 target: 213 step: 185 (compute_batch_value) cpuhp/1-14 [001] 10306.426541: cpuhp_exit: cpu: 0001 state: 185 step: 185 ret: 0 cpuhp/1-14 [001] 10306.426546: cpuhp_enter: cpu: 0001 target: 213 step: 186 (acpi_soft_cpu_online) cpuhp/1-14 [001] 10306.426553: cpuhp_exit: cpu: 0001 state: 186 step: 186 ret: 0 cpuhp/1-14 [001] 10306.426553: cpuhp_enter: cpu: 0001 target: 213 step: 187 (mce_cpu_online) cpuhp/1-14 [001] 10306.426597: cpuhp_exit: cpu: 0001 state: 187 step: 187 ret: 0 cpuhp/1-14 [001] 10306.426606: cpuhp_enter: cpu: 0001 target: 213 step: 188 (console_cpu_notify) cpuhp/1-14 [001] 10306.426607: cpuhp_exit: cpu: 0001 state: 188 step: 188 ret: 0 cpuhp/1-14 [001] 10306.426611: cpuhp_enter: cpu: 0001 target: 213 step: 189 (msr_device_create [msr]) cpuhp/1-14 [001] 10306.426665: cpuhp_exit: cpu: 0001 state: 189 step: 189 ret: 0 cpuhp/1-14 [001] 10306.426667: cpuhp_enter: cpu: 0001 target: 213 step: 212 (sched_cpu_activate) cpuhp/1-14 [001] 10306.426670: cpuhp_exit: cpu: 0001 state: 212 step: 212 ret: 0 Notice the -16 failure on hv_synic_cleanup.
