I just found that "ACPI: processor: idle: Optimize ACPI idle driver registration" depends on the change about cpuhp_setup_state in the commit [1]. Or many CPUs don't create cpuidle directory. What is the crash? Do you have releated trace? [1] https://lore.kernel.org/all/20240529133446.28446-2-Jonathan.Cameron@huawei.com/ > > > --------------- > > Rafael J.
