Re: UEFI boot hangs after loader

I set LOADER_DEFAULT_INTERP=4th and went in /usr/src/stand and re-made the
binaries in /boot but this doesn't solve the problem.  It did copy
/boot/loader_4th.efi to /boot/loader.efi which is (according to uefi(8)
which is what is called from /boot/boot1.efi and which contains the strings
I see on the console before the hang.  But it must then call / read
something else and I don't think it can find it.  Not sure why it doesn't
produce an error message.  I *think* it may be something to do with EFI
variables, but as efibootmgr doesn't work I can't explore this, despite
efirt being in the kernel.

Suggestions received welcomed, and new suggestions / leads to follow also
very much welcomed.
