    For the last several kernel releases after updating with ukuu I get a

    /dev/root: can’t open blockdev
    Kernel panic – not syncing : VFS: Unable to mount root fs on unknown-block(0,0)

    i’m able to go back and boot from the last known working kernel

    then run

    sudo update-initramfs -u -k version

    sudo update-grub

    and finally I can reboot using the latest kernel.

      Looks like the initramfs was not generated after installation. Do you have a separate boot partition and does it have enough space?
