Thomas Gleixner f97960fbdd kernel/printk: Block cpuhotplug callback when tasks are frozen ... The recent conversion of the console hotplug notifier to the state machine missed the fact, that the notifier only operated on the non frozen transitions. As a consequence the console_lock/unlock() pair is also invoked during suspend, which results in a lockdep warning. Restore the previous state by making the lock/unlock conditional on !tasks_frozen.
