After LoadImage is called, the EFI stub of the kernel image determines where the runtime kernel is going to be decompressed to (and I think relocates zImage if necessary), and reserves this area, before actually jumping to the zImage: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/driver...
This always felt somewhat precarious to me.
Could you possibly:
- add 'set debug=linux' in your grub.cfg and paste the logs
- add some printouts to arm32-stub.c
Is kernel v4.19.55 fine or should I use 5.2-rc7?
Well, you're seeing the issue on 4.19.55, so I think we should investigate that. The only value I would see would be a sanity check if the behaviour still exists with 5.2-rc7 (and if it doesn't use that as help to determine what's going on).
I would be surprised if the behaviour has changed.
