I found the problem: I happened to upgrade to 4.12 at the same time and neglected to enable this new option: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2c93e790e8253552227bf9b46a8d49dca3f71b06 And failed to notice that the uhci-hcd module consequently went AWOL. I've learned to read my kernel configuration commits and not automatically assume core-updates is broken ;-) I guess now we're just waiting for Hydra to finish the x86* builds.
