Comment 15 for bug 1864533

2.04-1ubuntu12.2 broke boot on my machine. It doesn't work with kernels that don't have CONFIG_EFI_STUB=y configured. This really needs to fall back to the old mode if EFI handover is not supported by the kernel.

Also, after using a kernel with CONFIG_EFI_STUB=y it still failed to boot one of my machines with root specified by UUID. I was able to workaround it by manually specifying the boot device with /dev/nvme0n1p2 at the grub menu, and then specifying GRUB_DISABLE_LINUX_UUID=true in /etc/default/grub.
