[08:12] <waveform> ikonia, I certainly tested back on the first point release, but I can't recall if the second point release was re-tested. I'll spin up a copy in a mo and see what's up
[08:31] <waveform> ikonia, I'm afraid it boots happily for me -- just to double check, specifically I'm using the image from http://cdimage.ubuntu.com/releases/jammy/release/ubuntu-22.04.2-preinstalled-server-arm64+raspi.img.xz -- could you let me know exactly which image you're using and (if it's different) I can see if I can figure out what's going on
[08:39] <ikonia> waveform: that's perfect, validation that it 'did' work before I invest more time, is what I  needed, thank you
[08:52] <waveform> ikonia, no prob -- if it's not getting past the rainbow screen (which is produced by the tertiary start4.elf bootloader) that *typically* means it's having some issue finding/loading one of: the relevant base device tree (should be bcm2710-rpi-zero-2.dtb), the kernel (vmlinuz in our case) or initrd.img
