Title:
  grub-efi-riscv64-bin 2.12-5ubuntu9 fails with "relocation overflow"

Status in grub2 package in Ubuntu:
  In Progress

Bug description:
  I have a virtual machine with 48 GiB RAM which booted fine before the
  package grub-efi-riscv64 was update to 2.12-5ubuntu9 on 2025-03-21.

  Rebooting the machine fails with "relocation overflow"

  RISC-V EDK2 firmware version 2024.11-5
  Press ESCAPE within 5 seconds for boot options relocation overflow
  Aborted. Press any key to exit.

  When I change the RAM size to 4 GiB booting works fine.

  This bug is release critical for 25.04.

  Best regards

  Heinrich
