Description

[Martin Shuman [:Marty]]

Attachment: SmartCollection_log.txt

Description:
If the user selects one of the Smart Collections on the homescreen, the device will display a black screen for several seconds, and then the device will restart itself.

Repro Steps:
1) Update a Flame device to BuildID: 20141016040204

no longer repros

Comment 4

[Marcia Knous [:marcia]]

Discussed with tchung. Even though this doesn't repro on the tbox build we are leaving the bug open until the regular build comes out tomorrow. At that time if the bug doesn't repro it can be closed out.

Comment 5

[Marcia Knous [:marcia]]

Using Flame and:

Gaia   abef62c0623e5504a97b4fd411e879a67b285b52
SourceStamp ae1dfa192faf
BuildID 20141017040208
Version 36.0a1
v. 184

This is still happening intermittently. After an OTA today the first 4 times I pressed the "Around Me" Smart Collection the entire device rebooted. The 5th time it did not happen.

Comment 6

[Peter Bylenga [:PBylenga]]

Requesting a window since we can still reproduce let's find what caused it.

Comment 7

[Tony Chung [:tchung]]

+ kevin grandon and Ran from E.me to help.  Do you guys know why this is happening?   this is a smoketest blocker that only happens on trunk, and not other branches.

Comment 8

[Kevin Grandon :kgrandon]

Nothing has changed recently in smart collections, so let's get the regression window. My hunch is that this is indexedDB based, and possibly the one that is causing other issues.

is comment 1 not clear on a range?   from what i can see, it sounds like gecko is the same, but gaia changes from: 

Gecko (works) 77f3ca1fe052 to Gecko (broken) 9fe9bace9ed5

Oh right, I didn't see that, I assume this is from comment 2, and in that it shows as gaia is the same, but a difference in gecko.

Comment 12

[Kevin Grandon :kgrandon]

Looks like this is the regression range? http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=9fe9bace9ed5&tochange=77f3ca1fe052

Comment 13

[Jayme Mercado [:JMercado] (Inactive 3/4/2016)]

I am looking into this issue again and have almost found the regression window (it is a gaia issue).  The build from yesterday that I was unable to repro on actually can reproduce this issue.  

Some things to note: This issue requires a restart to begin but sometimes requires up to 5 restarts before it will begin.  A symptom that indicates that a build might reproduce this issue are if the screen flashes when pressing a collection (but does not restart) and the black screen from the title is also not necissarily something that always occurs (the restart can take anywhere from instantly to 10 seconds and the longer it is the more you will see a black screen.

I will have the regression-window very soon, definitely before EOD.

Comment 14

[Kevin Grandon :kgrandon]

This feels like it could also be bug 994190, but let's see what the regression window comes up with.

Comment 15

[Jayme Mercado [:JMercado] (Inactive 3/4/2016)]

Forgive me I mistyped gaia when I meant gecko earlier, hasty typing is no good.  Here is the window.  This issue was hard because there is another crash issue when pressing the left most collection as soon as able but shows no other symptoms of this bug.  I plan to investigate this issue more on Monday.

Comment 16

[Kevin Grandon :kgrandon]

Thank you for the clarification and getting that window. Unfortunately it feels incorrect to me. I'm going to see if I can try without the patches from bug 994190. It might also be tricky to bisect this because that bug was landed, reverted, and re-landed. This could interfere with bisection. I don't have any concrete evidence of bug 994190, but based on what other people are seeing, it seems likely.

Kevin any update here? Its been more than a couple days and QA is reporting the same smoketest failure, so appreciate urgent help :)

Comment 18

I am unable to reproduce this on the latest build. Adding qawanted to see if they are still seeing this issue:

I am able to reproduce this issue on the latest 2.2 Nightly build 

Actual Result - As soon as the homescreen comes up and I click on a Smart Collection icon the device will reset.

I am NOT able to repro on the latest 2.2 Tinderbox build

Actual results - if I click on a smart collection icon immediately upon homescreen boot I will see the homescreen redraw once but then everything works fine - if I wait a few seconds on homescreen boot then everything works fine.

Comment 20

[Kevin Grandon :kgrandon]

Hmm, seems like there is still a bug here, but odd that the two builds are behaving differently.

Comment 21

[Kevin Grandon :kgrandon]

Based on comment 19 it seems that we have landed something in gecko that changes the behavior here. It seems that the original STR here no longer reproduces, so going to close this as worksforme.

I'm also unable to reproduce the "redraw" as mentioned in comment 19, but there may still be a bug. Please open another bug to track this issue, or reopen this one if it reproduces after the next nightly build.

Comment 22

[Marcia Knous [:marcia]]

I still have seen this intermittently doing an OTA on the User build, most recently on a 2.1 device where I have not seen it before.

Last seen on nightly:

Gaia   1e48e3e40e0780c0cd07a3457e5fe2efeeb542d1
SourceStamp 09fb60a37850
BuildID 20141023001201
Version 34.0
v188

Selected the Music collection and the phone rebooted. I updated to:

Gaia   0f76e0baac733cca56d0140e954c5f446ebc061f
SourceStamp 7d78ff7d25b6
BuildID 20141023161200
Version 34.0
v188

And it did not reproduce following the same STR.

Since it happened on 2.1 I think we might want to keep our eyes open for this bug on both branches.

Comment 23

[Marcia Knous [:marcia]]

reopening, as I am able to reproduce this on trunk today using the original steps. I selected the default collection "Music" following the OTA and the phone rebooted. I did not get the typical geolocation prompt before this happened.

Gaia   f46d56d812480bff7f3b35e8cacbedfa4d49edc5
SourceStamp d8de0d7e52e0
BuildID 20141023160203
Version 36.0a1
v188

Is it possible this has something to do with not getting the geolocation prompt?

Did you do an 2.0 -> 2.1 upgrade or an 2.1 -> 2.1 update?

Comment 25

[Gregor Wagner [:gwagner]]

Can we get a logcat with the exact timing information when the crash happens? I don't see anything in the logcat that shows that the device rebooted.

Updated 2.1->2.1. Will work on getting a better logcat

Comment 27

[Oliver Nelson [:oliverthor]]

This issue has not been encountered by our the smoke team at Q-Analysts in either the nightly build from yesterday, 20141027040237, or today: 20141028040202
Removing the smoketest keyword for now but we will keep an eye out to see if the issue crops up again and report back.

Attachment: reset_logcat.txt

Along with Oliver I can no longer reproduce this issue on the latest builds.  I went back to a build I kenw I could reproduce it on in order to grab the logcat.  In this logcat I pressed the collection at 13:43:27.
