Ah, well now I have an explanation:
One should always be skeptical of out-of-tree drivers.

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.
