May I ask: if you ran into this a few months ago (implying that the
affected system was misconfigured at that time), how is it that you
didn't fix the configuration at that point?  (I'm genuinely curious
about how people would run into the same class of failure twice on the
same system, since once you've fixed grub-pc/install_devices you should
be good for future upgrades.)
