With a default virio nic whose MAC does not match and I see the exact same output.
I repeated that with a Xenial instance and it fails in the same way; so I suspect there's something misconfigured w.r.t the MAC on the boot params; or possible since this is hardware, something is going on with the MAC addrs on the system with the e1000e nics.
So, what's happening here is the BOOTIF parameter specifies a MAC of a device, but that device is *not* found; then we see the errors here.
So let's get confirmation that the BOOTIF parameter mac matches with one or more of the interfaces on the system.
I recreated this same failure by booting a bionic instance with these parameters:
ip=:::: amused- guinea: BOOTIF ip6=off BOOTIF= 01-00-25- 90-4c-f0- 38
