I looked into this issue and it turns out that the problem is completely
different from what I originally guessed.
I think Ubuntu builds platform-pci as a module by default and
mkinitramfs doesn't include it in the initrd but it is required by
blkfront and netfront.

Could you please rebuild your initramfs making sure that platform-pci is
included (add platform-pci to /etc/initramfs-tools/modules) and try
again?
