Code:

EFI does not provide protocol 8b843e20-8132-4852-90cc-551a4e4a7f1c

I'm not sure how to interpret this, though.

That GUID is EFI_DEVICE_PATH_TO_TEXT_PROTOCOL_GUID; it represents the EFI functionality for converting a device path into a printable representation.

Ironically, iPXE uses that protocol only for debugging purposes; before enabling DEBUG=efi_init it wouldn't even have tried to locate the protocol. You can temporarily hack around the missing protocol by commenting out the line

Code:

    DBGC_EFI_DEVPATH ( systab, efi_loaded_image_path );

in interface/efi/efi_init.c. That should get you past this particular error and hopefully will reveal what the real original problem was.
