Hi, i recently switch for my suspend2idle tests from Raspberry Pi Bullseye to Bookworm. After that testing suspend2idle shows a new warning which i never saw before: HDMI Sink doesn't support RGB, something's wrong. Platform: Raspberry Pi 3 B+ Kernel: 6.12-rc1 Kernel config: arm/multi_v7_defconfig I applied this downstream patch [1], but this doesn't help. Any ideas?
