[Bug 1503731] Re: 8086:0f31 Ubuntu 15.04-15.10 freezes totally

[Vincent Gerris]

Hi Christopher,

Why did you ask to file a new bug to be made regarding to kernel?
I have reported a similar bug and it seems that at least one of the issues is 
quite throughly pinned down to that one that can be worked around with the 
cstate=1 or 2 for some others. Bay Trail and some successor platforms are 
affected. 
Wouldn't we prefer to keep things centralised?
Does Canonical have any contacts with intel to spearpoint this horrible bug?
I have seen thousands of users complaining and those are just the ones that do 
report.
So this is very likely to be related to:
https://bugzilla.kernel.org/show_bug.cgi?id=109051

The bisect of the kernel commit might to be :
https://bugs.freedesktop.org/show_bug.cgi?id=88012#c23

Somebody at least pitched it to intel and I replied:
https://communities.intel.com/thread/60984

Please do not ask many people to bisect kernels if it might already be
done, it's very daunting and there is no point for the people affected
by the bug, right?

Current work arounds are running a pre-3.17 kernel and use cstate=1 (this works 
for my Yoga 2 11 but affects battery life quite a lot):
http://askubuntu.com/questions/749349/how-to-set-intel-idle-max-cstate-1
or for some cstate=2. 

For anyone looking for more workarounds, checkout the
bugzilla.kernel.org bug, there are some more options.

And PLEASE, ANYONE having contacts with intel, alert them!
I am not sure if they are aware of this issue and I can't imagine they are not, 
but it would certainly help to try and put the pressure up.

Thanks, hope this helps.

[Bug 1503731] Re: 8086:0f31 Ubuntu 15.04-15.10 freezes totally

[jbMacAZ]

I've been following these freeze issues since kernel 4.2.  cstate is no
longer as effective since 4.6-rc7+ and 4.5.4+.

The known relevant commits are (from bugzilla #109051):

Freezing started after 3.16.7 with commit 
31685c258e0b0ad6aa486c5ec001382cf8a64212 
freezing worsened again between 4.1 and 4.2 with commit 
8fb55197e64d5988ec57b54e973daeea72c3f2ff
Reverting these commits in later kernels does not solve the problem.  But for 
some users, it extends run time before the next freeze, sometimes 
substantially.  intel_idle.max_cstate={0,1} has helped the most users the most, 
but it is a just a bandaid, not always effective.

The most recent kernels have rendered the ..cstate argument ineffective.
Other improvements in the kernel have reduced my freeze rate from < 30
minutes to about 10 hours.  At those rates, it could take a month to
bisect.

Freezing only seems to occur on Intel processors (atom and later).  The
freeze rates vary widely from minutes to weeks.  It has dependencies on
the particular Intel processor & revision, the hardware platform and the
kernel version.  Linux distro does not seem to matter much.  I have
experienced freezes with Ubuntu, Mint, Manjaro, and Android_x86 on
multiple platforms (Asus T100CHI & 2 Dell laptops) For me, cstate worked
to prevent freezes until very recent kernels.

As an intermittent problem, most freeze reports have been dismissed with
"It's not in my arena".  I believe this a cluster of problems requiring
concurrent fixes.  I'm not sure what Ubuntu can do to solve what seems
to be obvious upstream kernel problems.

Maybe Canonical can exert some influence on kernel.org to work on these
freezes rather than  breaking features that work while they push the
bleeding edge outward.  Many thousands of systems are affected, some of
which belong to IT professions who influence equipment purchase and
configuration for large corporations.  An 18 month old fatal bug is a PR
disaster waiting to happen.  By fatal I mean that the freeze can
irreparably corrupt an installed system (and I've had to re-install
twice so far.)

Yuriy, if the WORKAROUND doesn't work for you, then this report has nothing to 
do with your problem. Hence, it will help immensely if you filed a new report 
with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

[Christopher M. Penalver]

Chris Rainey, to advise, given this is Lauchpad (downstream reporting
system) it's impossible to mark it a duplicate of an freedesktop.org
(upstream reporting system) report, or any other reporting system. Also,
this is not considered being tracked at bugzilla, as this hasn't been
confirmed to be related.

Despite that, this report (downstream) is still pending
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1503731/comments/12
. Given your belief there is a commonality to an upstream report, it
would help to provide evidence of it by confirming the regression commit
noted in the upstream report is indeed the same for your hardware.

It looks like my issue is a combination of i915 and intel_pstates.

I'm following the thread at this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=88012


After switching my DELL Inspiron 3646 to the 3.16 kernel, I've had little to no 
trouble(even stressing the system using:  glmark2 --run-forever).

I got my 3.16 kernel here:  http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.16.7-ckt18-utopic/

Hope this helps !!

[Bug 1503731] Re: 8086:0f31 Ubuntu 15.04-15.10 freezes totally

[Christopher M. Penalver]

Chris Rainey, the next step is to fully commit bisect from kernel 3.16
to 3.19 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Please file a bug at [1] running drm-intel-nightly and attach dmesg from
boot with drm.debug=14 module parameter set.
