[Bug 2083150] Re: loader/efi/peimage.c:829:peimage: cannot load multiple images

[Heinrich Schuchardt]

Here is another example of an error which remains obscure without the
peimage error message:

Title:
  loader/efi/peimage.c:829:peimage: cannot load multiple images

Status in grub2 package in Ubuntu:
  New

Bug description:
  Version: 2.12-5ubuntu5

  I am using /usr/lib/grub/riscv64-efi/monolithic/grubriscv64.efi from
  the Oracular release.

  When executing `linux, initrd, device-tree, boot` I saw an error

      "error: cannot load image."

  in the GRUB console.

  I enabled debug=all and then it showed more:

  loader/efi/peimage.c:829:peimage: cannot load multiple images
  error: cannot load image.

  Please, do not expect a normal user to know about the debug variable.
  The message in /efi/peimage.c should be displayed without
  debug=peimage. Please, reconsider debian/patches/peimage-fixup-
  grub_error-grub_dprintf.patch. In most of the cases we should keep
  grub_error.

  I do not understand why we error out if the linux command is executed
  multiple times. I would expect only the last binary to be loaded and
  executed.

  Best regards

  Heinrich
