We faced this issue too, it was caused by having the initrd and vmlinuz from a previous Ubuntu ISO
``` KERNEL vmlinuz # <= should be from casper/vmlinuz in Ubuntu ISO INITRD initrd # <= should be from casper/initrd in Ubuntu ISO APPEND root=/dev/ram0 ramdisk_size=1500000 ip=dhcp cloud-config-url=http://192.168.0.2/autoinstall.yaml url=http://192.168.0.2/ubuntu-22.04.3-live-server-amd64.iso autoinstall ```
See for example https://github.com/canonical/autoinstall-desktop#pxe-configuration
