Steps To Reproduce:
(1) Open below link to run static H264 video
storage.googleapis.com/chromiumos-test-assets-public/Shaka-Dash/switch_1080p_720p.mp4
(2) Run video in loop
(3)

Expected Result:
smooth video playback
Actual Result:
System hang after running video for for few loops

How frequently does this problem reproduce? (Always, sometimes, hard to
reproduce?)
Always
What is the impact to the user, and is there a workaround? If so, what is
it?

Do we perhaps know what was the last R58 version this did not reproduce in, would you be able to bisect please? Thank you.
Issue also observed while running h264 webrtc video in loop over night. 

Feedback report : 54157978930


This issue not observed while running resolution change video or apprtc loop back video on 9312.0.0/58.0.3015.0.
Issue also observed on  9325.0.0, 58.0.3021.0.
Thank you. To confirm my understanding, the initially reported issue (not the overnight run issue) is a regression between 9312.0.0 (good) and 9313.1.0 (bad)?
Yes, correct. 
Summary: Baytrail: Observing system hang while running static h264 resolution change video in loop (was: Sumo: Observing system hang while running static h264 resolution change video in loop)
Issue reproduced on kip device using static h264 resolution video on 9331.0.0, 58.0.3027.

This is perhaps related to changes for scaling matrix in 9313.0.0? Owen, would you be able to confirm please?
Do you mean the CL:
https://codereview.chromium.org/2702973002/.

But it doesn't looks harmful, but anyway, I will try by reverting the CL first.

Observed system hang issue while running youtube videos in autoplay on sumo device on 9334.2.0, 58.0.3029.6.

Feedback report:54597417355

Observed system hang while running https://storage.googleapis.com/chromiumos-test-assets-public/Shaka-Dash/480.webm video in loop.

Issue observed after disabling the hardware decode from about:flags and also observed in guest mode. 

Issue observed on sumo and kip on 9334.2.0, 58.0.3029.6

How long it is required to reproduce the issue?

I tried to play the resolution change video for 1 hour but cannot reproduce it.
(environment: 9347.0.0 Gnawty).

Besides, the comment #11 also indicate this is not a h264 / hardware codec issue. 
I wasn't able to find anything in the feedback reports, however I'm assuming they were submitted after hangs and restarts, so logs may not have been preserved.

Since we cannot reproduce this, would you be able to bisect this further to the exact last good and first bad Chrome OS version that this started happening on please? Thank you.
Owner: avkodipelli@chromium.org
FYI: cannot reproduce with the webm file on 9347.0.0 Gnawty after playing the video for more than 1 hour.
Avinash suspects this might be limited to CPU variant being used by Sumo, he's running some more tests to ascertain. 
Owner: owe...@chromium.org
This issue is observed only on baytrail devices(kip, sumo, Enguarde) with cpu type "Intel(R) Celeron(R) CPU N2940 @ 1.83GHz".

9334.5.0, 58.0.3029.12 is used for testing.

posciak@ all those above feedback reports were submitted after force reboot.
The 2940 is a higher end SKU, quad core with the newer frequency bin. 

Does this also happen to repro on a 2930 system? That would suggest this is a problem for just quad core.
bhthompson@, is there a good way to look up CPU breakdown for the board family? GE is too broad in its specification. There are a lot of baytrail devices and looking their CPU information up individually will take a few hours, would be great if we can cheat :).

Summary: Baytrail: Observing system hang while running static h264 resolution change video/youtube/webm videos in loop (was: Baytrail: Observing system hang while running static h264 resolution change video in loop)
Few more observations :
- We have 2 kip devices one with CPU N2830 and N2940, Issue is observed on device with N2940.
- I have tried few other devices with N2830(Ex:squawks) and issue not observed.
- Issue is observed with devices N2940(kip,sumo , enguarde)
- We don't have any device with N2930 with our team.

As this issue reproduced with other videos, I'm changing the title of the bug.  
We are going for beta promotion with the build Tuesday evening, any chance we can have a fix for this in that time?
It sounds like a CPU dependent issue. I am finding such device and trying to reproduce it. At the same time, I will file a bug to Intel.

But it is unlikely we can have a fix in Tuesday. 
I got one kip with N2940, will try to reproduce the issue.

Hi Avinash,

1. I would like to double confirm that the issue is still reproducible after disabling hardware decoding (said in comment #11).
2. How long it takes to reproduce the issue?

I can reproduce the issue locally. As said in comment#5, it is a regression between 9312.0.0 (good) and 9313.0.0 (bad).

Will try to identify the issue.
Owen. Did video_VideoSeek catch this bug?
We already knew it's a regression between 9312.0.0 and 9313.0.0. 

Besides, the issue took more than 10 mins to reproduce (sometimes even longer than 45 mins). So, I don't think video_VideoSeek would be able to catch it.
https://wmatrix.googleplex.com/platform/unfiltered?hide_missing=True&tests=video_VideoSeek&releases=tot&platforms=kip

Because it happens on both webm and h264 files, I first thought it was https://codereview.chromium.org/2656073003. But after reverting the CL, I can still reproduce the issue.

Now, I am doing bisect. But it takes time to reproduce the issue. The progress is slow.
Labels: -ReleaseBlock-Beta ReleaseBlock-Stable
Punting to stable, though this is a regression if it only happens on looping videos using the local player is is likely rare enough to be hit for beta at this point.
Bisect indicates the following commit introduces the issue.

https://chromium.googlesource.com/chromium/src.git/+/43364fb75871b5f530f4a63d8f78fe7a3134efbb

But unfortunately, this is just a false alarm. Before the revert, chrome just fallback to sw codec, so that this issue cannot be reproduced.

Just reproduced the issue on 9293.0.0. That's before the reverted change.
Cc: bhthompson@chromium.org
Identify this as a regression between 9242 ~ 9243.

I loos at the difference between the two version.
https://crosland.corp.google.com/log/9242.0.0..9243.0.0

I think it is https://chromium-review.googlesource.com/c/431315/

which converts BayTrail systems to kernel 4.4. But still need to verify. 
(Un?)fortunately, I have tested with TOT 4.4 kernel on 9242.0.0 for two hours but cannot reproduce the issue. 

So, it maybe something else or we just fixed it on 4.4 kernel.
Interesting, I can reproduce the issue with kernel 4.4 at the following commit
https://chromium-review.googlesource.com/435059. (i.e., the version at 9243.0.0)

So maybe we have it fixed in TOT.
Owner: bhthompson@chromium.org
I think we are just lucky in #34. I still can reproduce the issue with TOT kernel. 

Hi Bernie,
do you think we can revert "https://chromium-review.googlesource.com/c/431315/".

Filed a partner issue:
https://buganizer.corp.google.com/issues/36635254
I don't think we can wholesale revert back to 3.18 in the release branch at this point, it has other dependencies and we have not been validating 3.18 on these since the CL went in two months ago so it is risky.

Thanks for digging into this, lets see what the partner issue finds before we do something drastic. 
Bernie. Is it for sure Baytrail will switch to 4.4 in m58?

Owen. Can you enable vaapi vda logs, reproduce the issue, and attach it here? 
The rest of the Baytrail systems do convert in 58 as we have it, we had some systems converted to 4.4 in 57 so this is not really a new issue most likely.

I would be hesitant to go back at this point, we have other dependencies on 4.4 that could make reverting to 3.18 at this point problematic.

It is also strange that there are some 0x00s appends in the end of the file.

The zeros might suggest that we lost the remainder of the log when the system hanged and had to be force rebooted, potentially with some more info that could give us an idea what happened? How did you capture the log?

Any update here? This is marked as a stable blocker, and we are nearing stable promotion for 58. 
No, there is no response from Intel. Just ping them again. https://buganizer.corp.google.com/issues/36635254

This was broken by the conversion to kernel 4.4, the drm patches were _not_ ported forward, so we are hitting an old issue.

Sadly the switch to kernel 4.4 triggered an old issue, except that it
is now worse. Now we need to also disable CPU cores to make the
machine stable. So let's do that.

  https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/6e6d872a3556392f7c4e0bea3950644ca5b3d4c4

commit 6e6d872a3556392f7c4e0bea3950644ca5b3d4c4
Author: Rajat Jain <rajatja@google.com>

Baytrails: Disable CPU cores > 3

This is a workaround similar to
https://chromium-review.googlesource.com/c/484652/
except that we keep 3 cores instead of 2.
