No idea
Do you have any idea what that string could be? Maybe some memory that really is in use by EL3 isn't declared as such in the EFI memory map?
Well, the issue is gone when I reduced initial initrd size to reasonable value.
Can you try some memory tester in user space then? I‘m not sure the issue is actually gone, it might just not get exposed on boot anymore.
Indeed. stress-ng --vm 1 --vm-bytes 75% --vm-method all --verify -t 10m -v hungs the system, but unfortunately there is no output on console, even with loglevel=8
