So we seem to have thermal or ACPI regression in v4.9-rc3.
It is possible. Can you add either add printk in acpi_processor_ppc_has_changed() or use ftrace and see do you get to these functions acpi_processor_ppc_init() acpi_processor_ppc_has_changed() acpi_processor_ppc_notifier() ? When temperature limit is reached acpi_processor_ppc_notifier() should be called. Thanks, Srinivas
