here is the call trace when a dock is plugged:
in kacpi_notify_wq:
acpi_bus_notify->blocking_notifier_call_chain->acpi_dock_notifier_call->acpi_os_hotplug_execute
then kacpi_hp_wq is running:
acpi_os_execute_hp_deferred->acpi_os_wait_events_complete->flush_workqueue(kacpi_notify_wq)
so you're right that this is a circular locking issue.
