** Description changed: [Impact] When booting a kernel >= 5.7 via GRUB on an arm64 server, the EFI stub falsely reports a firmware bug: EFI stub: Booting Linux Kernel... EFI stub: EFI_RNG_PROTOCOL unavailable, no randomness supplied EFI stub: ERROR: FIRMWARE BUG: efi_loaded_image_t::image_base has bogus value EFI stub: Using DTB from configuration table EFI stub: Exiting boot services and installing virtual address map...

[Fix] https://github.com/rhboot/grub2/commit/1d5ef08216edec4d31d0e10cfdb30b5ebfef7a45 - [Regression Impact] + [Where Problems Could Occur] + The fix is in GRUB's EFI loader, so problems would likely appear early in the boot of the kernel (during EFI stub processing).
