Not sure what the severity should be, or which package I should file a bug
against, but I've appended some typical output below that may or may not be
useful:

The fact that both grub-install and efibootmgr are getting EINTR here
(albeit with different subsequent effects) suggests to me that the
problem is at a lower level. This looks like it's probably a kernel
bug, or maybe (though less likely IMO) a bug in the efivar userspace
library. Reassigning to the kernel for now.
I suspect "strace -f -s 1024 grub-install --target=x86_64-efi" and
"strace -f -s 1024 efibootmgr" might be helpful, along with checking
dmesg to see if the kernel is logging any errors there.

Thanks for the advice to check dmesg - the kernel seems to think
there is a firmware bug, which somehow I didn't notice earlier:

The output from the other commands is fairly long, so I've left copies at

kernel has disabled efi:
