I have packaged up 20170707 for testing in my ppa available
https://launchpad.net/~chiluk/+archive/ubuntu/1700373
These are versioned as
Z=3.20170511.1~ubuntu17.04.0+lp1700373
Y=3.20160714.1+lp1700373b2
X=3.20151106.1+lp1700373b2
I'd appreciate some help testing these before I push on the SRU.
@Dave
Yes - please repackage. I see no reason to force 20170511 instead of
20170707. But I would prefer to release (after verification) Y and Z
before releasing X.
In terms of tracking bugs, shall we retitle this bug for 20170707 and
reopen it for Zesty? As there's nothing in flight at the moment
The 20170707 version would be ideal to SRU for Xenial (and Zesty) since
it fixes the hyperthreading defect on Skylake, Skylake-X, and Kabylake.
The Kabylake fix is especially important. There is a lot of demand from
users for a fix, and bios updates really aren't an ideal way to deliver
it.

@hmh, thanks for the heads up.
@rbasak, As the X and Y uploads haven't made it through the SRU yet. Do
you want me to repackage with 20170707?

Relevant information:
I have uploaded to Debian yesterday, and it has already been auto-
migrated to Ubuntu Artful Aardvark, the newest intel-microcode release
(base date: 20170707).
This new upstream release fixes the hyper-threading issue (as well as
several other undisclosed issues) on Skylake
I have repackaged this again based on the discussion from the ubuntu-
release mailing list discussion. I have avoided any other changes that
didn't appear absolutely necessary. I have uploaded the resulting
packages to my ppa available here

10:58 xnox: thanks, that's very useful to know. What's the the
difference between early initramfs and normal runtime from the kernel/hardware
perspective? I didn't think there was any distinction? But there has been talk
of Trusty not having early initramfs support. I don't follow why t
Pardon my ignorance, can someone please clarify in more details meaning
of "require early initramfs loading code" from comment #12? Because
clearly some people will go ahead and update it in Trusty anyways.
Judging from other comments new microcode may break something that is
unlikely to be presen
FTR, after discussion with Dave on IRC, I rejected his other uploads
from the queue because they were straight backports. The SRU team has
already rejected this due to a lack of mitigation for regression risk to
users, but Dave had missed the thread in ubuntu-release@ about this.

Who is "we", please? Is this a decision of the Ubuntu Foundations team?
Or are you saying that you won't work on it, but it's open for others to
attempt?

I should also mention that we will be following Debian's lead and not

reasons for this.

I just pushed uploads for this into the x, and y queues. I wanted to
hold off for a few days to give those on zesty/artful to sniff test this
before I pushed on the SRU.
I have tested this on X+skylake and X+sandy-bridge-e *(that was just to
