Comment 8 for bug 1633207

I realized that part of my former verification was caused by the kvm-in-lxd env I use to avoid needing too much metal. So I retried on x86 again as these code paths shouldn't be arch specific at all. And now I was able to recreate on x86 as well.

The summary looks like this now:
* - xenial - works
ppc4el - yakkety - fail
x86 - yakkety - fail
x86 - yakkety with 4.4 kernel - fail

Going on with debugging, but I'm on the Road the next few days - so it might take a bit unless someone else jumps in.
