Can you take a screenshot of this?

I would suggest raising this question on the grub-devel mailing list as

Installing works, but booting the installed system with GRUB doesn't
work. No idea yet what the problem is.

I don't know yet. This needs to be investigated by a GRUB developer.

You would need to install my test kernel first before stress-testing:
