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

Status in grub2 package in Ubuntu:
  New

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-basedarm64 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.
