Hi![...]quoted
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() ?
Ok, can do, let me recompile and reboot.
When temperature limit is reached acpi_processor_ppc_notifier() should be called.
No, that's not correct for ACPI passive trip points, is it? If I recall correctly, those should be monitored even when temperature is below them so that it does not reach them...?
