those changes might have caused this issue.
Are you happy to try rebuilding grub from source yourself? If so, I'd
suggest to rebuild without those f2fs changes included. If you're not
sure, let me know and I'll do a rebuild for you.

Excellent, and thanks for testing!
OK, so the patches from upstream have broken f2fs support for
you. Looking at the patches, I'm not seeing anything *obvious* there
that might be an issue. They're all trying to add checks to avoid
crashes with an invalid/corrupt f2fs filesystem.
Silly question: does your filesystem have errors? Does fsck.f2fs
report anything?

note stuck to the mini-bar saying "Paul: This fridge and
fittings are the correct way around and do not need altering"

# fsck.f2fs -f /dev/sda1
didn't report any errors.
I can continue testing - rebuild without patches in turn, to reveal patch which break f2fs support.
