In this case, one of my endpoint drivers was mismanaging a pci_dev_put() reference count, and that cascades to all its children and links, including the host bridge. Once I fix that (and the aforementioned problem (1)), it seems my problems go away. I'll let a v2 soak in my local environment, and unless I hear some news from Bartosz about OF_POPULATED to change my mind, I'll send it out eventually. Brian
