 # --- ARM64 console string ---
-# Covers QEMU virt (ttyAMA0), Ampere/RPi-equivalent PL011 (ttyAMA0), and
-# Graviton/16550-compat (ttyS0). Last `console=` becomes the system console.
+# Order matters: the LAST `console=` is the primary system console (where /dev/console
+# points and where init's stdout/stderr land). Earlier `console=` entries get mirrored
+# kernel output but don't carry process I/O.
+#
+# Covers Graviton/16550 (ttyS0) as secondary and QEMU virt / PL011 / Ampere (ttyAMA0)
+# as primary. ttyAMA0 must be last for `-nographic` QEMU + most ARM64 SBCs.
+#
+# `quiet` is intentionally omitted from the default entry while we stabilise the
+# generic ARM64 boot path. Add back once boots are reliable.
