@furmanek, Thanks for testing.
@Breno, Commit e47057151 was not applied to Xenial. It did not apply
cleanly because the following commit is already in Xenial as of
4.4.0-96(As Xenial SHA1 25e0720):
17d381054b1d6f4adc3db623b2066fff41b4dc1a
("KVM: PPC: Book3S HV: Reload HTM registers explicitly")
Commit 17d381054 came in from the 4.4.80 updates and does what commit e47057151
does and more. Per comment #18, it sounds like it fixes this bug. It would be
great if others affected by this bug could also test -proposed.

Christian, I am looking at 4.4 git repository and version -93 contains exactly the problem described here, it contains the commit# 46a704f8409f79fd66567ad3f8a7304830a84293 (as a97e978574f41ffcf1813c180aba2772d46fbb5b), but it does not include commit# e47057151422a67ce08747176fa21cb3b526a2c9.

[Bug 1709784] Re: KVM on 16.04.3 throws an error
Hi, there was a related case in bug 1664622. The TL;DR of this was: 1. even with all qemu patches identified by IBM and upstream while working on this the issue still showed up. 2. newer kernels (>=4.8, but also newer 4.4 kernels than those on the release itself worked - that matches the report here) 3. the conclusion was that nothing can/has-to be done for qemu [1] 4. there was no way to fix the initial 16.04.0 iso, but that was considered ok since 16.04.2 worked Mapping to this bug here it seems that a further update to 4.4 might have broken it "again" as identified by Gustavo in in this report. I added all this to complete the context for everybody else, but for now qemu stays at won't fix for the reasons and assumptions haven't changed since our last check on this issue. On the kernel surely if the identified two patches really need to go together a fix might be needed, but that is for the kernel Team to evaluate.
