This is now commit 37c3ec2d810f87ea ("arm64: topology: divorce MC scheduling domain from core_siblings") in arm64/for-next/core, causing system suspend on big.LITTLE systems to hang after shutting down the first CPU: $ echo mem > /sys/power/state PM: suspend entry (deep) PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.001 seconds) done. OOM killer disabled. Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. Disabling non-boot CPUs ... CPU1: shutdown psci: CPU1 killed. For me, it fails on the following big.LITTLE systems: R-Car H3 ES2.0 (4xCA57 + 4xCA53) R-Car M3-W (2xCA57 + 4xCA53) System supend still works fine on systems with big cores only: R-Car H3 ES1.0 (4xCA57 (4xCA53 disabled in firmware)) R-Car M3-N (2xCA57) Reverting this commit fixes the issue for me.
