The BCM2711 has both the older style hardware and the
new-to-RPi*'s gic. These two alternatives that do not
mention armstub8-gic.bin are having the BCM2711 use
the older, less capable type of hardware instead of
using the newer, more capable gic. (Or, at least,
that is what is explicitly initialized.)

You are better off with the solution that has the
[pi4] and armstub=3Darmstub8-gic.bin lines so that
the gic is explicitly initialized.

Hi Mark,

Oh I see, thanks again! I'll apply your reco= mmendation.
