[Bug 1947046] Re: EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary

[Pascal van Dam]

Good afternoon,

This also effects the https://cdimage.ubuntu.com/daily-live/current/jammy-desktop-arm64.iso
image. Currently I can boot debian arm64 UEFI ISOs and Fedora, but not the Jammy cd image using PI uefi.

Any idea when this fix will be incorporated on the ISO so can do further
testing?

Kind regards,

  Pascal van Dam

Title:
  EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k
  boundary

Status in grub2 package in Ubuntu:
  Fix Released
Status in grub2 source package in Jammy:
  Fix Released

Bug description:
  [Impact]
  Recent kernels emit the following error message when booting on arm64 platforms:

    EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k
  boundary

  While this doesn't appear to cause any functional issues - and indeed,
  the kernel commit that added the error[*] says "We can deal with this,
  but let's check for this condition anyway", it is still likely to
  cause user concern.

  [Test Case]
  Boot a recent kernel on an EFI-based arm64 system (impish will do, but the kernel patch is also hitting kernels in older releases). This message will be emitted after GRUB execs the kernel EFI stub.
