Hi to all,
I am running aarch64 as a headless server (without monitor attached). Since the last update it looks like it is booting - bit it is stuck somewhere. Not reachable via network. For debugging I attached a monitor and now it works again! I can reproduce it only boots fully if a monitor is attached since the last update. I already downgraded raspberrypi-bootloader without luck - problem persists. I added hdmi_force_hotplug=1 to /boot/config.txt - but this does not change anything. At the moment I can attach a monitor but that is not what I want... Any ideas to get it back booting fully without attached monitor?
