Hi Joseph, Tested with this kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.9-wily/ to be sure that the VM is booting as expected.

[Kernel-packages] [Bug 1555786] Re: [Hyper-V] VM with ubuntu 32bit with linux-next does not boot
Tested with upstream kernel 4.0 and 4.0.9 on a 32 bit VM. With both of this version VM booted as expected without issues. Also I tested with upstream kernel 4.1 and VM did not boot. I expect that the issue is present for first time in upstream kernel 4.1.
