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

[dann frazier]

@zyga: hm.. I wouldn't expect this to cause a functional problem,
perhaps what you are seeing is unrelated. Can you try adding 'earlycon
debug' to the kernel command line? If you see messages from the kernel
with that, it's likely something else.

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

Status in grub2 package in Ubuntu:
  In Progress

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.
