Hi. I am wondering whether there has been any resolution for this. I have just undertaken a similar processes - moving from an older emonsd image to the 01Feb24 image on a RPi3+. RPi boots fine without the emonpi board installed, but get continuous stream of “sysrq: HELP: …” messages, interspersed with occasional boot messages when booting with the board attached. Have flashed image twice, one with BalenaEtcher and also with Raspberry Pi Imager with the same result. Many thanks
