In Snakeoil / Linux Kernel / Current Kernel is 6.10-rpi7-rpi-v8. There is another kernel 6.10-rpi7-rpi-2712 which I can select, save and reboot. But it always goes back to the v8 kernel. Works OK with X86 version.
While waiting for the fix, is there something I can edit in /Boot/Config.Txt? Bookworm is now using initramfs (config, initrd.img, system.map, vmlinuz files) rather than kernel8.img (for Rpi4). I have tried searching for clues but a lot of info point back to using gz files or kernel.
Once I can figure this out, I am hoping a custom RT kernel will work!
