Hi,
Since I read of the vt bug being fixed, I tried another 4.4 kernel.
I also upgraded my SSD to the latest firmware.
I have:

Hi,
I've been on holiday, hence the delay in response.
In the mean time I have experienced freezes again with both the intel and the
rc5 kernel.
Still no solution I guess.
I will reinstall windoze when I have time and upgrade the SSD firmware as some
suggested.
Although I already read reports
Vincent Gerris, the next step is to fully reverse commit bisect from
kernel 4.6-rc1 to 4.7-rc5 in order to identify the last bad commit,
followed immediately by the first good one. Once this good commit has
been identified, it may be reviewed for backporting. Could you please do
this following
Hi Christopher,
I am not sure what you mean, I tested 4.6 rc4 which I mentioned freezing in the
second post.
Maybe a misunderstanding?
I am running this now:

Vincent Gerris, you were requested back in April to test the then latest
mainline kernel, and you were making comments that didn't mention this.
Despite this, the latest mainline kernel is 4.7-rc5 (not drm-intel-
nightly). Could you please advise to the results of this?

I am running the 4.7 994 kernel from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/
My builtin wireless doesn't work, but I have bluetooth working and I can
watch video and copy files with that on without a freeze.
I hope this helps anyone and I hope at some point
this issue is not solved. I have not had any suggestions on how to continue to
troubleshoot this.
I was trying to test the 4.7 intel kernel mentioned here:

Hi Andrew,
Thanks for pointing that out,as you can see I think I have identified the
source of my issue. I don't see the relation to your bug directly. As long as
my btusb module is not loaded I seem to have no issues.
Makes the purpose of the laptop kind of useless,because I play music over
Vincent, i am also tracking a similar bug (if not the same one). I too
have been testing the latest upstream kernels as instructed. They all
seem to have the same bug for me. My problems started after upgrading
from 14.04 as well. Using my grub2 boot menu to select the oldest kernel

Hi,
I think I got a little further!
The 4.4.0-21 seemed to work flawlessly, untill I found out that when enabling
bluetooth I got the freezes.
It even worked fine at first, but because the sound was crappy I changed the
headphones profile to A2DP and then the freezes started as soon as I had
Hi,
I installed the latest included kernel:
Linux vincent-Lenovo-Yoga-2-11 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18
18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
I will test that and then the 4.6.0-rc4 after.
Is there anything patched there that could be a solution to the fix?
Thank you
Vincent Gerris, could you please test the latest mainline kernel
(4.6-rc4) and advise to the results?

The bcmwl driver did not work, so I had to use this solution to make it work as
a workaround:
on goes the testing. Windows 10 installation with all drivers installed gave no
freezes (although it was slow :) ).
Played many hours of video and run updates without issues.
Reinstalled Ubuntu 16.04, and got hang issues right after updating.
Installed 4.4.0-18 which froze also.
I enabled
The 4.4.0-16 kernel gave me a freeze too recently. Ran really long
without issues but on a next boot after testing the 4.6.0-rc2 it froze.
So I am basically back to where I was when I reported this, with the difference
that the BIOS is the latest now.
I am not sure how to continue

Hi,
I started having problems after the upgrade to 16.04 beta.
I think the last kernel before the update from 15.10 was 4.2.0-35.

I guess it is that.
The last freezes happened after playing video.
I installed the
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.5

- it happened a few times when running apt-get update or upgrade (from a
