Hello,
I first want to thank the Ubuntu devs, I've been a very long time Ubuntu
user and appreciate what you guys do to make and keep it such a great
distro.
That being said, I too am affected by this bug on a fresh 17.04 install,
I first noticed it after updating from 4.10.0-19 to 4.10.0-20,
I'm seeing this too.
Every time it has locked up I've been scrolling in chrome.

With that comment do you mean to say you're positive that 4.12 will have
a fix, or do you mean to say you're positive that 4.11 will NOT have a
fix?

System soft-freezes, BUG:
Just a note that you can also find the 4.8 kernel (image and headers) at
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D, and if you
install the deb files from there, you don't need to enable the yakkety
repos.

In my experience it was only after I added the Intel-specific drivers
for my video card (in the Dell XPS 15 9560) that the crashing happened
on 4.10.x. So, I'm just running 4.8.x until 4.12 comes out or someone
magical advises here that the fix has gone into a minor release of 4.10
(which I read
just had a crash without virtualbox, so it's not that
4.8.x seems to be stable

System soft-freezes, BUG: unable to handle
Generally I'm having stability issue since
- upgraded to 17.04 - xorg freezes with kernel Ooops
- installed virtualbox - resume fails
I removed virtualbox and suspend seems to be ok
The bug opener also has vbox modules loaded, which makes me wonder if this all
coz by virtualbox?
anyone else
My VERY shitty workaround has been to add the yakkety repositories back
to my machine with apt edit-sources, then install and use the 4.8.x
kernel from there. :/

Yes, the bug is indeed the same as that one.

Unfortunately I was still able to reproduce. Here's the current trace,
this time without arbitrary line cutoffs.
While this report, too, has chrome as the "comm" I've also seen compiz
being the "culprit."
