Approximately every other day video will freeze for no reason at all and no specific time between freezes.

Approximately every other day video will freeze for no reason at all and no specific time between freezes.

[Chris]

To elaborate on this. The video is frozen to include the clock however I
can move the mouse cursor around the screen. I can not however switch
between window desktops. This happened on 28 Sept 2015 after an uptime
of 6d20h6m, on 30 Sept after an uptime of 1d23h10m and today after an
uptime of 1d20h12m. I have reported this bug at the Ubuntu Launchpad
site and per an individual there I was instructed to go from running
kernel 4.0.0-997-generic #201503310205 SMP Tue Mar
31 02:07:04 UTC 2015 (I could not report this bug because apport-collect
would error with 'non supported kernel') so he had me switch to kernel
3.19.0-30-generic #33~14.04.1-Ubuntu SMP Tue Sep 22 09:27:00 UTC 2015.
System info is Ubuntu 14.04.3 LTS Gnome-Shell 3.12.2. Computer is a Dell
Optiplex 780 with Bios A15. There are no errors shown in my syslog as in
previous problems where "Hangcheck...render ring idle" would show up.
All background processes such as Fetchmail, Procmail, Spam Assassin,
ClamAv and cron jobs continue to run normally.

Any assistance would be appreciated.

Hi

Firstly you should open a bug on bugzilla and provide all relevant
information there like a copy of your dmesg and Xorg.0.log output of lspci
-nn

You should also state what versions of various packages you're using if
you're and what you've tried changing

Also try the latest rc kernel to see if that fixes your issue

Are you using any kernel overrides like fbc, rc7 or forcing atomic? If so
switch them off - if you don't know what they are then don't worry

Cheers

Mike

Mike, thanks for the reply. I reported this in bug
https://bugs.freedesktop.org/show_bug.cgi?id=91495 with the stipulation
that sometimes the error [drm:i915_hangcheck_elapsed [i915]] *ERROR*
Hangcheck timer elapsed... render ring idle would show in my syslog.
That seems to not be the case anymore as it hasn't shown up since 28
July 2015. I've also reported the latest issue to Ubuntu Launchpad
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1497627 which
states simply Periodically video will freeze for no reason at all and no
specific time between freezes. Christopher M. Penalver who I assume is a
member of the Ubuntu kernel bug team has had me try several things as
noted in my Ubuntu bug report above. The latest was today when he had me
install and attempt to boot into the latest upstream kernels at
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D which I did this
morning. Of those listed starting at the top of the list this is what
happened when trying to boot into them

v4.3-rc3-unstable - Boot process would begin but would not complete
v4.3-rc2-unstable - Same as above
v4.3-rc1-unstable - Same as above
v4.2.3-unstable - Boot process completed however I noticed when
switching desktop windows a flickering of the video

The video flickering is slight most times but it's there. I'm currently
running kernel

I'm currently running kernel

Re: Approximately every other day video will freeze for no reason at all and no specific time between freezes.

[Martin Steigerwald]

Hi Chris, hi Intel graphics developers,

I have seen exactly this issue on ThinkPad T520 with Sandybridge graphics.

With one exception: At least sometimes I have been able to switch to tty1 and 
do killall -u <affecteduser> to get back to sddm login screen.

I didn´t do anything about it so far. Driver is running in uxa mode, cause 
with sna I experienced hard freezes with mouse freezing and even data loss. I 
lost my GPG public key ring after a hard freeze after a gpg --recv-keys 
operation (restored from backup meanwhile). This was at DebConf and a 
developer I worked with recommended me to switch from SNA to UXA. And some 
time ago I had it that kwin sometimes told me it restarted compositing due to 
a hang in the graphics driver.

I find freezing issues extremely hard to debug. First off often they happen 
when I am not willing to spend even a single minute on them. Second: What to 
do anyway? On a hard freeze, I could try Sys-Rq key combo to sync disk 
contents, and I think I may better enable it anyway to avoid data loss in 
those situations, and hope that *some* information on *why* the hard freeze 
happened still lands in kern.log or Xorg log. On soft freezes I can do 
something if I can still switch to tty1. But what? I have no idea what 
information I can gather *efficiently* to provide at least a somewhat 
meaningful initial bug report within less than 15 to 30 minutes. I don´t just 
want to do *something* in that case, but I want something that has a good 
chance on giving a real insight on why the bug is happened and a good hint at 
what can be done to fix it.

git-bisect is out of question for me for something that happens so 
irregularily. It would take an insane amount of time with running kernels that 
are probably way to unstable for production use – as it may include pre-rc1 
kernels - anyway. Even tough I go to the limits on this machine regarding 
production use, this is still a production machine and I usually wait till rc2 
kernels to try out a new kernel.

So I appreciate any pointers what to *efficiently* do about issues like this. 
In case I miss any documentated bug triaging howto please point me to it. 
Ideally some kind of bug-reporting tool would be nice. Just run a script which 
collects all data that can be helpful into a file that I can attach to a bug 
report.


That said in general I am really quite happy with the Intel drivers.

Hi

I'm not certain but I think I faced the same issue when I was enabling
atomic on my sandybridge laptop, it was like one of the planes stopped
being updated. When I reported it all that time ago I was told atomic was
considered unstable and I shouldn't be using it.

Has atomic been switched on recently?

Unfortunately the laptop is no longer functional so I can't test any of
this out

In my case I'm able to SSH into the box from my tablet and save any
pertinent log files. I've attached them to my two bug reports noted in
my earlier post but I don't know if they actually show anything or not.
Each time there is a freeze I run, per Chris Wilson of this list,
cat /sys/class/drm/card0/error which always reports 'no error state
collected'. I also run cat /sys/kernel/debug/dri/0/i915_swizzle_info
again as requested by Chris Wilson. The results are always the same

bit6 swizzle for X-tiling = none
bit6 swizzle for Y-tiling = none
DDC = 0x00200010
DDC2 = 0x00300030
C0DRB3 = 0x0030
C1DRB3 = 0x0010

And not knowing what I'm looking for I don't know if the above is ok or
not. 

I get into a real quandary when the guru's here in this list ask me to
try something such as running kernel 4.0.0-997-generic #201503310205 SMP
Tue Mar31 02:07:04 UTC 2015 from here
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ 
then when I go to report it at Ubuntu I'm told don't run this kernel
it's unsupported run this one 3.19.0-30-generic #33~14.04.1-Ubuntu SMP.
After noting a freeze after 1 1/2 days I was told by the Ubuntu Guru to
start with the newest upstream kernel from here
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and to attempt
install until I got one to work which in this case was kernel
4.2.3-040203-generic #201510030832 SMP Sat Oct 3 12:34:31 UTC 2015. 

This 'video freeze' issue actually started back on 09/13/2014 when at
that time my syslog would show kernel: [173977.808008]
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render
ring idle. At that time I was running kernel Ubuntu 3.13.0-36.63-generic
3.13.11.6. This continued on through Ubuntu kernel versions
3.13.0-37.64-generic 3.13.11.7, 3.13.0-39.66-generic 3.13.11.8,
3.13.0-40.69-generic 3.13.11.10, 3.14.0-031400-generic,
3.13.0-44.73-generic 3.13.11-ckt12, 3.13.0-45.74-generic 3.13.11-ckt13,
3.19.0-031900-generic (kernel@tangerine) During this freeze I noticed
the following in my syslog - this was all prior to my reboot right after
the freeze - http://pastebin.com/MpfiGqLe Continuing with kernel
versions affected- 3.13.0-46.76-generic 3.13.11-ckt15,
4.0.0-040000rc2-generic - when running this kernel another trace was
generated http://pastebin.com/VghUmcjx booted into kernel
4.0.0-040000rc4-generic call trace generated here also -
http://pastebin.com/RdbWfFYb booted into kernel 4.0.0-997-generic from
here http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ which
at the time was the most current.

I'd be happy to provide any other information that I can. The
'hangcheck....'error is no longer seen even though the freeze symptoms
remain the same.
