Where might this weirdness come from? > only node 3 is powered according to the BMC, but node 4 and node 1 have power, too. See picture. It happens on official firmware (2.1.0) and alternate alpine variant. Observed on my Turing Pi 2.5.2 board and happens on every boot .

In the picture you see the LEDs for node 1,3,4 on, although the nodes 1 and 4 are not powered. Node 1 is an Orin NX, not powered according to the photos on, but not booting in that configuration, at least no link and no serial. Node 3 is a CM4, the only node powered. Node 4 ist a RK1, not powered but network link ist up and actually it is reachable 🤯 https://cdn.discordapp.com/attachments/1179360051442487427/1505355444778963104/image.png?ex=6a0a5302&is=6a090182&hm=5dd79928c4863d1db561e6ec74250ad745bb54f951a65e6c4e586bb9c44143d8&
