Ah, that one is fixed by 15930da42f89 ("workqueue: Don't call
cpumask_test_cpu() with -1 CPU in wq_update_node_max_active()"). I have a
hard time imagining that having anything to do with console being quiet tho.
It's a cpumask bit test targeting cpu -1 and the result gets overwritten
later during boot.
Thanks.
