This worked:
killall grub-mkconfig grub-probe
Of course, this means that this part of the upgrade did not complete.
The messages about failing i/o on that sector went on after the kill, but
eventually stopped. I think the kernel continued retrying to
exhaustion, but when the kernel gave up, there was no longer
any process saying to try again. All in all, it had been retrying for
something like 24 hours.
