GPIO madness.
Dear Lazyweb, riddle me this:
1. Boot Pi with HDMI monitor attached: works fine.
2. Boot without monitor: all GPIO inputs "flap" about once a second.
3. Plug in monitor: 10 seconds later, inputs start behaving normally.
4. Unplug monitor: remains good. Until reboot.WTF?
Raspberry Pi 4 Model B Rev 1.5, Debian GNU/Linux 12 (bookworm) 12.11. Two different Pis, same behavior.
