@rhansen, your bug might be a different one, since ip=dhcp is processed by the initramfs, while I'm talking about the kernel, before the initramfs gets to run.

The bug is still there in Xenial.
I noticed that it doesn't happen in all hardware; I've seen it in *some* real clients and under VirtualBox, while I haven't been able to reproduce it under KVM.

Example from Xenial:
$ grep 'model name' /proc/cpuinfo
model name : Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz

$ dmesg

I also tried with "nohibernate", it's not related to hibernation.
